题目：催款

Dear Sirs,

　　Account No.8756

　　As you are usually very prompt in settling your accounts, we wonder whether there is any special reason why we have not received payment of the above account, already a month overdue.

　　We think you may not have received the statement of account we sent you on 30th August showing the balance of US$ 80,000 you owe. We send you a copy and hope it may have your early attention.

　　Yours faithfully,

　　xxx
