Subject：Overdue account
Dear Sir，
Our records indicate that we have not received your payment which was due on December 5th. We hope this was just an oversight and you will be able to remit the funds due immediately.
The amount due on your account is￥1，500.
This amount includes any applicable late charges and/or fees.
If your records reflect that you made this payment prior to the date of this letter, you still need to contact us so that the discrepancy can be resolved and any necessary corrections can be made on your account.
Yours sincerely，
Margaret Bing
敬启者：
我们的记录显示还没有收到您于12月5日到期的付款。我们希望这只是一次疏忽，并希望您能马上支付逾期款项。
逾期欠款金额为1500元。
如果您的记录表明在收到此信的日期之前您已经支付过该款项，您还是需要联系我们，这样，我们就能解决我们的记录差异问题，并为您的账户做出必要的修正。
