英语投诉信怎么写？？？

结构要点：
投诉信是对产品或服务表示不满的信件，一般分三个部分：1. 提出投诉内容；2. 说明具体情况；3. 提出解决办法。

语言注意点：
投诉信应重点表明投诉的原因，叙事应客观、准确、简洁。最后提出的解决方法应切实可行。在表达自己的不满时，语言要把握分寸，不失风度。

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...

下面是关于产品投诉的范文：
Dear Sir or Madam,

A few months ago I purchased a washing machine (Sanyo XQB50-68) from your department store. After a few weeks I found that it had seriously damaged that clothes. I asked you to change one for me, which you did. Now I want to ask you to change this one for me again.
This one does not damage my clothes any more, but I have found that it tangles the clothes seriously and when it automatically begins to spin the water out, the machine shakes so heavily that it stops by itself. In the instruction booklet you have not mentioned this defect and neither have you told the user how to solve the problem. I am quite annoyed by the fact that sometimes when I came back from work to take the clothes out to dry, they were still unwashed. When I at home. I have to tend it frequently to untwist the entangled clothes. Is that what you call your machine “fully automatic”. Please change a new one for me that will not entangle the clothes. Otherwise, I would ask you to give my money back, or I would complain to the Consumers’ Association.

Yours sincerely,
Fan Yang

几个月前我从您的百货公司购买了一台洗衣机 (Sanyo XQB50-68)。经过几个星期，我发现它严重破坏衣服。我请你为我换一台，你换了。我现在想请你在为我换一台。
这一个不会破坏我的衣服了，但我发现它严重的缠结衣服，当它自动将水抽干时，机器震动的更严重，它自己停止了。在说明书你有没有提到这一缺陷，并也没有告诉用户如何解决这个问题。我很恼火,有时当我工作回来,把衣服拿去凉干,但他们仍未洗完。当我在家里。我不得不照料它频繁地解开纠缠的衣服。难道这就是你叫你的机器“完全自动”。请为我换个新的，不会搅衣服。否则，我想请你给我退款，否则我会投诉到消费者协会。

我是新手，希望亲采纳噢~(*^__^*) 嘻嘻

投诉信一般可分为三部分：第一部分说明事由，点明你写信的意图；第二部分写明投诉的原因，要展开说明，或者讲具体理由，或者谈问题的具体体现方式；最后一部分一般是提建议，说明你所期望的解决方法，并表达希望问题（包括针对产品或服务的质量等问题进行投诉，目的是为了让对方解决你碰到的问题）得到尽快解决的强烈愿望，并对有关人员做出的努力表示感谢

如果你英文不是很好的话，一边查词典一边写。如果你是问格式怎么写的话，按照中文的格式翻译过来就OK了
