Dear Mr. Harding,

亲爱的哈丁先生：

I am terribly sorry for the overdue balance on our account. It turns out that the last invoice we received from you was somehow misplaced. Would it be possible to grant us a 5-day payment extension? I can ensure that you will receive the outstanding balance by next Thursday.

非常抱歉我们逾期未能付清账款。原来是上次您的发票寄来之后不知怎么找不到了。我想问一下可不可以再延长五天的支付期限呢?我保证下周四之前您可以收到未付账款。

I appreciate it very much for your understanding.

非常感谢您的谅解。

Yours faithfully,

Catherine Jones
