投诉信，主要用于因某件事情未受到应有的待遇而投诉某人或某单位。因为在生活中不经常用到投诉信，所以大家可能都不是很清楚投诉信要怎么写，那么在这里我就和大家分享一下吧。

就下述文章写一篇投诉信：

你在某商店没了一双皮鞋，穿了不到一个月就发现坏了，去信要求这家商店退货赔款。

Dear Mr. Manager,

I’m writing to complain about the poor quality of shoes in your store. One month ago I bought a pair of shoes from your store. It wears well as I like.However, it was broken in less than a month. It disappointed me much.

I choose to complain to you because I’m sure you will be able to take back the shoes and pay an indemnity.

Yours faithfully

Tom

Dear Sir/Madam,

I am writing to you to complain about your hotel. I had a terrible stay in room 5012 of your hotel from the 24th to the 26th of August 2002, when I came to Guangzhou on business.

Firstly, the air-conditioning in my room could not be turned down or switched off. When I asked the reception staff to do something about it, they laughed and told me it was better than being hot. I asked your front of house manager and she told me she would send someone to my room immediately. No-one came. As a result, I was very cold every time I was in the room.

Secondly, I found the bathroom dirty and the hot water was always warm.

Thirdly, the noise at night was extremely loud and I found it difficult to sleep. I asked to change rooms, but was told it was impossible because the hotel was full.

I paid a lot for my stay in your hotel and expect much better service from such a well-known hotel. In future, I will not be staying at your hotel again and will inform my business associates of the terrible service.

Yours faithfully,

J. T. Hakala.
