投诉信

投诉信一般是针对质量低劣的产品或者服务，其送寄对象应该是对方主管部门的负责人。写投诉信的目的是为了让对方同情你的遭遇或者碰到的问题，继而给出你所期望的解决方法。因此，写这类信件最重要的一点是要实事求是，一定要遵守“简明、公正”的原则，切勿夸大其词，引起对方的反感。

投诉信中应该包含的内容有：你所投诉的问题；该问题给你造成的不良后果；与投诉有关的重要依据，如商品简要说明、购买日期地点等；你所希望的解决方法和最后结果。此外，还可以向对方建议解决问题的最后日期，并表示对所投诉问题的妥善解决充满信心。

投诉信一般可分为三段：第一段说明信的主要意思，即提出要解决的问题，以及解决问题的重要性；第二段可以解释一下详细的情况，提出与投诉有关的重要依据；最后一段一般是提建议，说出你所期望的解决方法。

以下是一封样信：

Dear Sir,

Enclosed is one sample of the envelopes which your delivery truck left in our office yesterday. We wish, however, to exchange them for the correct size, or obtain a refund.

When our supply secretary selected and purchased official envelopes in your store last week on December 12, she asked that size L be sent to our office. The size we received is small, and of course it does not serve our needs. The sales receipt is #3968, dated December 12, written by salesclerk #189.

Please send us the correct size L envelopes in exactly the same style and color, or if this is not available now, cash refund of $ 50.50. Thank you very much.
