TechVision Electronics Co., Ltd.
88 Innovation Road, Shenzhen, China

Dear Sir or Madam,

I am writing to express my dissatisfaction with the TechVision Pro X1 laptop (Order No. TV-20240820-7731) that I purchased from your official online store on August 20, 2024.

Unfortunately, within just six weeks of normal use, the laptop has developed a serious defect: the screen flickers intermittently and occasionally goes completely black for several seconds. I have already tried updating the display drivers and performing a system reset as suggested by your online troubleshooting guide, but the issue persists. Given that this product is still well within the one-year warranty period, I find this level of quality to be unacceptable for a device marketed as a premium product.

I would therefore like to request either a full replacement with a new, defect-free unit or a complete refund of the purchase price of ¥6,999. I have attached a copy of my receipt and a short video demonstrating the screen issue for your reference.

I trust that you will treat this matter with the urgency it deserves. I look forward to your prompt response within five business days. Should I not receive a satisfactory resolution, I will have no choice but to escalate this matter to the Consumer Protection Association.

Yours faithfully,
Li Ming

尊敬的先生/女士：

我写此信是为了表达我对2024年8月20日从贵公司官方网店购买的创视Pro X1笔记本电脑（订单号：TV-20240820-7731）的不满。

遗憾的是，在正常使用仅六周后，该笔记本电脑出现了严重的质量缺陷：屏幕间歇性闪烁，偶尔会完全黑屏数秒。我已经按照贵司在线故障排除指南的建议，尝试更新了显卡驱动并执行了系统重置，但问题依然存在。鉴于该产品仍在一年的保修期内，对于一款定位为高端产品的设备而言，这样的质量水平令人无法接受。

因此，我希望贵司能够为我更换一台全新的、无缺陷的产品，或者全额退还购买价格人民币6,999元。我已随信附上购买凭证的副本以及一段展示屏幕问题的短视频，供您参考。

我相信贵司会以应有的重视态度来处理此事。我期待在五个工作日内收到您的及时回复。如果未能得到令人满意的解决方案，我将不得不将此问题提交至消费者协会处理。

此致敬礼

Customer Support Team
ShopEase Online Marketplace
168 Commerce Avenue, Hangzhou, China

Dear Customer Support Team,

I am writing to formally lodge a complaint regarding the severely delayed delivery of my order (Order No. SE-20241010-4458), which was placed on October 10, 2024.

According to the estimated delivery date provided at the time of purchase, my package was supposed to arrive by October 17. However, as of today — nearly three weeks later — I have yet to receive my order. Worse still, the tracking information has not been updated since October 14, when the status merely read "In transit to destination city." I have attempted to contact your logistics partner on three separate occasions, but each time I was met with vague responses and no concrete resolution.

This prolonged delay has caused me considerable inconvenience, as the items were intended as a birthday gift that has now long passed. I respectfully request that you either expedite the delivery immediately with a guaranteed arrival date, or issue a full refund including the shipping fee of ¥15.

I would appreciate a substantive update on this matter within 48 hours. Thank you for your attention, and I hope we can resolve this amicably.

Yours sincerely,
Wang Fang

尊敬的客户支持团队：

我写此信正式投诉我的订单（订单号：SE-20241010-4458）严重延迟送达的问题，该订单于2024年10月10日下单。

根据购买时提供的预计送达日期，我的包裹本应在10月17日前到达。然而截至今日——将近三周过去了——我仍未收到订单。更糟糕的是，物流追踪信息自10月14日起就没有更新过，当时状态仅显示"正在运往目的城市"。我已三次尝试联系贵司的物流合作伙伴，但每次都只得到含糊其辞的回复，没有任何实质性的解决方案。

这种长时间的延误给我造成了极大的不便，因为这些商品原本是作为生日礼物准备的，而生日早已过去。我恳请贵司要么立即加快配送并保证确切的到达日期，要么全额退款，包括15元的运费。

我希望能在48小时内收到关于此事的实质性进展回复。感谢您的关注，希望我们能友好地解决这一问题。

【英文范文】

September 22, 2024

The General Manager
La Maison Dorée Restaurant
25 Riverside Promenade, Shanghai, China

Dear General Manager,

I am writing to bring to your attention a deeply disappointing dining experience my family and I had at your restaurant on the evening of September 20, 2024.

We had made a reservation for four people at 7:00 PM to celebrate my mother's 60th birthday. Upon arrival, we were kept waiting for over 25 minutes before being seated, despite our confirmed booking. Once seated, it took an additional 40 minutes for our orders to be taken, and the waiter displayed a noticeably impatient and dismissive attitude when we asked questions about the menu. When the food finally arrived, two of the dishes were lukewarm, clearly having sat under the heat lamp for far too long. To make matters worse, when I politely raised these concerns with the waiter, he responded with a shrug and walked away without offering any apology or remedy.

For a restaurant that positions itself as a fine-dining establishment and charges premium prices, this level of service falls woefully short of expectations. I request a formal written apology and would also like to know what measures you intend to take to ensure such incidents do not recur.

I have been a loyal patron of your restaurant for several years, and it is precisely because of this that I feel compelled to share my feedback. I look forward to hearing from you soon.

Yours sincerely,
Zhang Wei

总经理
金色庄园餐厅
中国上海市滨江步道25号

尊敬的总经理：

我写此信是想向您反映2024年9月20日晚，我和家人在贵餐厅一次令人深感失望的用餐体验。

我们预订了晚上7点的四人位，为我的母亲庆祝60岁生日。到达后，尽管我们有确认过的预订，仍被让等了超过25分钟才入座。入座后，又等了40分钟才有服务员来点单，而且当我们询问菜品相关问题时，服务员表现出明显的不耐烦和轻慢态度。当菜品终于上桌时，其中两道菜只是温热的，显然在保温灯下放置了太久。更令人不满的是，当我礼貌地向服务员提出这些问题时，他只是耸了耸肩就走开了，没有任何道歉或补救措施。

对于一家自定位为高端餐饮并收取高昂价格的餐厅来说，这样的服务水平远远低于预期。我要求贵餐厅出具正式的书面道歉，同时也想了解您打算采取什么措施来确保此类事件不再发生。

我一直是贵餐厅多年来的忠实顾客，正因如此，我才觉得有必要分享我的反馈。期待您的回复。

Guest Relations Department
Grand Horizon Hotel Group
500 Business Central District, Beijing, China

Dear Guest Relations Manager,

I am writing to express my profound disappointment with my recent stay at your Grand Horizon Beijing Central branch from December 3 to December 6, 2024 (Confirmation No. GH-BJ-88210).

Upon checking into Room 1507, I immediately noticed that the bathroom had not been properly cleaned — there were visible stains on the bathtub and used towels left behind from the previous guest. The air conditioning unit emitted an unusually loud rattling noise throughout the night, making it virtually impossible to sleep. When I contacted the front desk at 11:30 PM to request a room change, I was informed that no alternative rooms were available and was told, rather curtly, to "try using earplugs."

As a frequent business traveler who has stayed at your hotel chain in multiple cities, I found this experience to be far below the standards that Grand Horizon claims to uphold. The lack of basic cleanliness, combined with the unprofessional response from your front desk staff, has significantly undermined my confidence in your brand.

I am requesting a full refund for the three-night stay totaling ¥3,600, as well as a written explanation of how you plan to address these issues. I have attached photographs documenting the room conditions for your review.

I await your response within seven business days.

Yours faithfully,

宾客关系部
宏景酒店集团
中国北京市商务中央区500号

尊敬的宾客关系经理：

我写此信是为了表达我对2024年12月3日至12月6日入住贵集团北京宏景中央分店（确认号：GH-BJ-88210）的极度失望。

入住1507号房间后，我立即发现浴室没有被妥善清洁——浴缸上有明显的污渍，还留有上一位客人用过的毛巾。空调整晚发出异常响亮的嘎嘎声，几乎无法入睡。当我在晚上11:30联系前台要求换房时，被告知没有可用房间，并且被相当生硬地告知"试试用耳塞"。

作为一名经常在多个城市入住贵酒店连锁的商务旅客，我认为这次体验远远低于宏景酒店所宣称的标准。基本的清洁问题加上前台工作人员不专业的回应，严重动摇了我对贵品牌的信心。

我要求全额退还三晚共计3,600元的住宿费用，并要求贵方提供书面说明，阐述将如何解决这些问题。我已附上记录房间状况的照片供您查阅。

我等待您在七个工作日内给予回复。

August 18, 2024

Customer Relations Department
SkyWing Airlines
1 Aviation Plaza, Guangzhou, China

Dear Sir or Madam,

I am writing to file a formal complaint regarding the abrupt cancellation of flight SW-3382 from Guangzhou to Tokyo, originally scheduled for departure at 9:15 AM on August 15, 2024 (Booking Reference: SKW-TYO-5590).

I arrived at the airport at 6:30 AM as recommended, only to discover at the check-in counter that the flight had been cancelled. No prior notification — whether by email, SMS, or phone call — was sent to me despite my having provided all relevant contact details at the time of booking. The earliest alternative flight offered was not until 8:00 PM the following day, resulting in a delay of over 30 hours. This caused me to miss a critical business meeting in Tokyo and incur additional accommodation expenses of ¥850.

Under the Civil Aviation Administration's regulations on flight disruptions, passengers are entitled to compensation for cancellations made without adequate notice. I am therefore requesting the statutory compensation of ¥1,200, as well as reimbursement for the hotel expenses incurred due to the overnight delay, for which I have attached the receipt.

I expect a written acknowledgment of this complaint and a timeline for the processing of my compensation claim within ten business days. I trust that SkyWing Airlines values its customers and will resolve this matter fairly.

Yours faithfully,
Liu Yang

天翼航空公司
中国广州市航空广场1号

尊敬的先生/女士：

我写此信正式投诉天翼航空SW-3382航班（广州至东京）被突然取消一事，该航班原定起飞时间为2024年8月15日上午9:15（预订编号：SKW-TYO-5590）。

我按照建议于早上6:30到达机场，却在值机柜台得知航班已被取消。尽管我在预订时提供了所有相关联系方式，但我没有收到任何事先通知——无论是电子邮件、短信还是电话。所提供的最早替代航班要到第二天晚上8:00才有，导致延误超过30小时。这使我错过了在东京的一个重要商务会议，并额外产生了850元的住宿费用。

根据民航局关于航班中断的规定，旅客有权因未提前充分通知的航班取消获得赔偿。因此，我要求法定赔偿金1,200元，以及因过夜延误产生的酒店费用报销，相关收据已随信附上。

我期望在十个工作日内收到对此投诉的书面确认以及赔偿申请处理的时间表。我相信天翼航空重视其客户，并将公正地解决此事。

Property Management Office
Greenfield Residential Community
36 Lakeside Road, Chengdu, China

Dear Property Manager,

I am writing to formally report a persistent noise disturbance issue caused by the residents of Apartment 12B, directly above my unit (Apartment 11B), which has been ongoing for approximately two months.

On numerous occasions — particularly between 11:00 PM and 2:00 AM — I have been subjected to excessive noise emanating from the apartment above, including loud music, heavy footsteps, and the dragging of furniture across the floor. I have documented at least fifteen such incidents since early November, with dates and times carefully recorded. I have personally approached the residents of 12B on two occasions to politely raise the issue, but unfortunately, my requests have been disregarded, and the noise has continued unabated.

This sustained disturbance has severely affected my sleep quality and daily well-being. As a resident who pays property management fees in full and on time, I believe I am entitled to a peaceful living environment as stipulated in the community's residential guidelines.

I respectfully request that the property management office issue a formal warning to the residents of Apartment 12B and take appropriate enforcement action if the disturbance persists. I would also appreciate it if you could provide me with a written update on the actions taken within one week.

Thank you for your prompt attention to this matter.

Yours sincerely,

物业管理处
绿田住宅小区
中国成都市湖滨路36号

尊敬的物业经理：

我写此信正式反映我楼上12B公寓住户长期制造噪音的问题，该问题已持续约两个月，严重影响了我（11B公寓）的正常生活。

在许多情况下——尤其是在晚上11:00至凌晨2:00之间——我不得不忍受楼上传来的过大噪音，包括大声播放音乐、沉重的脚步声以及拖动家具的声音。自11月初以来，我已记录了至少十五次此类事件，并仔细标注了日期和时间。我曾两次亲自上门礼貌地向12B住户提出此问题，但遗憾的是，我的请求被置之不理，噪音依然如故。

这种持续的干扰严重影响了我的睡眠质量和日常生活。作为一名按时足额缴纳物业费的住户，我认为自己有权享有小区居住公约中所规定的安宁居住环境。

我恳请物业管理处向12B住户发出正式警告，并在干扰持续的情况下采取适当的执行措施。同时，如果您能在一周内向我提供所采取行动的书面反馈，我将不胜感激。

感谢您对此事的及时关注。

Head Office — After-Sales Service Division
HomeStar Appliances Co., Ltd.
200 Industrial Park, Nanjing, China

Dear Sir or Madam,

I am writing to express my extreme frustration with the unacceptable after-sales service I have received regarding the repair of my HomeStar washing machine (Model HW-800, Serial No. HS20230615-4422), which was purchased on June 15, 2023 and is still under the two-year manufacturer's warranty.

The machine developed a drainage malfunction in early February. Since then, I have contacted your local service center on five separate occasions. Each time, I was given a different excuse: first, I was told that the technician was unavailable; then, that the required part was out of stock; on another occasion, my appointment was cancelled without notice; and most recently, I was informed that my case had been "transferred to another department" with no further follow-up. It has now been over four weeks, and my washing machine remains unrepaired.

This pattern of evasion and broken promises is not only unprofessional but also constitutes a breach of your company's stated warranty obligations. I am requesting that a qualified technician be dispatched to my home within three business days to carry out the necessary repair at no cost, in accordance with the warranty terms.

Should this matter remain unresolved, I will not hesitate to file a complaint with the local Bureau of Market Regulation and share my experience on consumer review platforms.

I look forward to your immediate action.

Yours faithfully,

中国南京市工业园区200号

尊敬的先生/女士：

我写此信表达我对家乐星洗衣机（型号HW-800，序列号HS20230615-4422）维修售后服务的不满。该洗衣机于2023年6月15日购买，目前仍在两年厂家保修期内。

该洗衣机在2月初出现了排水故障。此后，我先后五次联系贵司当地服务中心。每次都得到不同的借口：先是说技术人员没空，然后说所需零件缺货，还有一次预约被无故取消，最近一次被告知我的案例已"转至其他部门"，此后便再无跟进。至今已过去四周多，我的洗衣机仍未修好。

这种推诿和失信的模式不仅不专业，而且构成了对贵公司所承诺的保修义务的违反。我要求在三个工作日内派遣一名合格的技术人员到我家中，按照保修条款免费进行必要的维修。

如果此问题仍未得到解决，我将毫不犹豫地向当地市场监督管理局投诉，并在消费者评价平台上分享我的经历。

期待贵司立即采取行动。

ConnectPlus Telecommunications

Dear Billing Manager,

I am writing to dispute unauthorized charges that have appeared on my mobile phone bill for the billing cycle of January 15 to February 14, 2025 (Account No. CP-8821-5567).

My regular monthly plan costs ¥128 and has remained unchanged for the past year. However, upon reviewing my latest bill, I discovered two additional charges that I did not authorize: a "Premium Content Subscription" fee of ¥30 and a "Value-Added Service Package" fee of ¥25. I have never subscribed to, nor consented to, either of these services. Furthermore, I have received no confirmation messages or notifications regarding the activation of these services on my account.

I request that these unauthorized charges totaling ¥55 be immediately reversed and credited back to my account. Additionally, I ask that you investigate how these services were added without my explicit consent and provide me with a written explanation. I also request that you implement safeguards on my account to prevent any future unauthorized subscriptions.

I have been a ConnectPlus customer for over six years and have always paid my bills promptly. I trust that you will rectify this error swiftly and restore my confidence in your billing practices.

I look forward to your response within five business days.

Yours sincerely,

尊敬的账单经理：

我写此信是对2025年1月15日至2月14日账单周期内（账号：CP-8821-5567）出现的未经授权收费项目提出争议。

我的常规月度套餐费用为128元，过去一年一直未变。然而，在查看最新账单时，我发现两项我从未授权的额外收费：一笔30元的"高级内容订阅费"和一笔25元的"增值服务包费"。我从未订阅过也未同意开通这两项服务。此外，我也没有收到任何关于这些服务在我的账户上被激活的确认短信或通知。

我要求立即撤销这些未经授权的收费共计55元，并将其退还至我的账户。同时，我要求贵司调查这些服务是如何在未经我明确同意的情况下被添加的，并向我提供书面说明。我还要求贵司在我的账户上设置保护措施，以防止未来出现任何未经授权的订阅。

我作为联通PLUS的客户已超过六年，一直按时缴纳账单。我相信贵司会迅速纠正这一错误，恢复我对贵司计费系统的信心。

期待在五个工作日内收到您的回复。
