Dear XXX,

First of all please accept our sincere apology. Due to the careless mistake by our company driver, the delivery note that you have sign ed to us were lost. We are terribly sorry for our company’s mistake and hope to receive your kind understanding.

Please advise whether it is possible for you to sign the replacement delivery note to us for our processing.

We ensure we will not let this kind of mistake happen again in the future, and we are deeply sorry for all the inconvenience caused to your company.

含糊其詞話 - I believe the document was lost during transpotation /delivery. I'd like to apologize if there's any convenience caused.

如果真係要正本 - Please kindly have me back a new copy of the document by fax / email. Please sign and fax back the attached copy of the document...

言簡意精, 俾D信心自己!
