在当今商品经济时代，商品买卖活动非常普遍。在日常生活中，人们常会遇到对所购商品质量或售后服务不满意的情况，这时可以写投诉信(A Letter of Complaint )求得解决。投诉信与普通书信的格式基本相同。但要注意的是，写投诉信的目的是为了求得一个解决问题的办法而不是为了泄愤，因此写信时一定要注意态度诚恳、直截了当。

　　一般说来，一封投诉信应包括三个最基本的方面：

　　1.投诉内容。一般放在信的开头。常用的表达法有：

　　I am writing to you about... which I received/bought ...

　　I am going to complain about ...

　　I am sorry to have to return with this letter... which I received/bought...

　　2.投诉原因。一般讲述对商品质量或售后服务不满意的地方。常用的表达法有：

　　When we checked..., we noticed...

　　When I took... out of the bag and examined... closely, I found...

　　When I unpacked... and tried to use it, it did not work.

　　3.希望得到的结果。常用的表达法有：

　　Please let me know what you intend to do in this matter.

　　I am returning... under separate post and look forward to receiving a full refund of...

　　In view of the inconvenience that this has caused, I feel you should...

　　我们来看看下面这篇范文：

　　15 March, 2003

　　Dear Sir,

　　I am writing to you about a typewriter I ordered from you on 13 March, 2003.

　　When I unpacked the machine and tried to use it, I found the backspace key didn't work. Looking it over, I also found the line space regulator has been cracked.

　　As you know, the machine is unconditionally guaranteed for a year. Since you have no service man in this city I am obliged to return it to you. I hope you can send me a new one within a few days.

　　Yours truly,

　　Wang Ping

　　这是一封要求调换打字机的信。作者首先说明了要投诉的商品是一台打字机。接着作者抱怨了打字机的质量问题：退格键坏了，行距调节器破裂。由于打字机是无条件保修一年，而本市又没有维修人员，作者最后要求调换产品。信中列举的质量问题符合实际，调换的理由充分，作者的态度诚恳，因而调换的要求是合理的。
