I am sure you will agree that we have shown every consideration and now you fail to reply to our earlier requests for payment, I am afraid you leave us no choice but to take other steps to recover the amount due.
We are most reluctant to do anything from which your credit and reputation might suffer and even now we prepare to give you a further opportunity to put the matter right.We therefore propose to give you 15 days to clear your account,
Yours faithfully,
xxx
催款函主题：三度索取欠款
亲爱的先生：
第8756号账单
我们于9月8日及9月18日两次去函要求结付80，000美元欠款，单至今未收到贵方任何答复，对此我们感到难于理解。我们希望贵方至少得解释为什么账款至今未付。
我想你们也知道我们对贵方多方关照，但你们对我们先前的两次询函不作答复。你们这样做恐怕已经使我们别无选择，只能采取其他步骤来收回欠款。
我们极不愿意做任何损害你们信誉的任何事情。即使现在我们还准备再给你们一次机会来挽回此事。因此，我们再给你们15天时间来结清账目。
