大部分公司对于合理的索赔和投诉都会给予肯定的答复。通常公司是欢迎顾客的投诉的，这样它们就可以知道产品或是服务都有哪些不足，从而改善和提高。答复投诉和索赔信应遵循下面几个原则：

1. Reveal at the beginning that the claim is being granted.
2. Explain the circumstances.
3. Close courteously and positively.

当卖方是错误发生的责任方时，卖方在答复中需要解释清楚错误情形。如果不解释清楚，买方就会认为当前的交易不是一桩好买卖，可能会转而寻找其他卖家。如果解释过于庞杂，买方可能没有兴趣看或是认为卖方业务运作过于复杂。因此在解释错误原因时说清楚主要的几点即可。

承认错误后还应承诺改正错误和改善以后的工作。这是重新赢得客户信任的一个重要步骤。注意：可别说以后再也不会犯错，因为错误是不可避免的。

最后，还要表示继续合作的希望。毕竟，要赢得客户并不容易，所以要维护好客户以免流失。

下面是一封对索赔和投诉的肯定回复。由于是卖方发错货，我们来看看卖方是怎么答复的：
