投诉信的目的是为了获取更好的服务，对已出现的问题求得尽快的、妥善的解决，它通常是买方由于对收到的货物不满而书写的。起因可以是：货物未按时到达；货物虽抵达，但与订单所述不同；货物有损毁现象；货物数量短缺或多余；货物质量与样品不符；服务不合理以及收费过高等。一般来说，上述问题不严重，才写投诉信，望对方尽快妥善解决。
范文
Dear Sirs，
Our Order No. 879
The above goods arrived on January 2. We regret to have to tell you that we cannot accept them because of short weight.
On examining the goods we found that all drums of orange juice weigh short by from 1 to 5 kilograms, totaling 300 kilograms. As the drums were intact, it is obvious that orange juice was short weight before shipment.
Considering this is the first transaction between us，we hope you will promptly remedy it. We will dispatch the goods back to you but all the charges should be for your account.
Very truly yours,
[Name]
[Title]

主题：合同号879
上述货物于1月2日到达：我方很遗憾告知您方由于此批货物短重，我们无法签收。
经检查此批货物，我们发现桶装桔汁每单位短重1到5千克不等，总短重300千克由于桶都是完整的，明显桔汁在装运前就短重。
考虑到这是我们之间的初次交易，我方希望你们能立即采取补救措施。我方将把货物返回给你们，但是所有费用应由您方承担。
