帮忙翻译3句话，谢谢很急啊~~十万火急

1，贵公司要求装船时间延长的申请请求我公司不能接受，所以，如果在装船日期之内没有装船的话，请取消信用证。

试着翻第一条。

We are sorry to tell you that we cannot accept your request of extending the due date of the shipment, therefore, please reject the credit license if you cannot satisfy the due date.

非专业的，信用证是专有名词，翻不来。不好意思。

楼上的一看就不是专业的。
你这是外贸英语里的句子吧。
可惜，我老翘这门课，现在才发现这门很重要（很多外贸类证要考）。希望你好好读这门课。 加油！！
