We did not suspect you had not sent the email to Amy requesting us to apply this new symbol in Feb 2008. However, she had left our company in Jan 2008 as we already informed you in the previous email dated March 18.???? Therefore, we had been unable to receive the email, which had left us unaware of your request???.
We are apologizing for letting this happen. It was beyond our expectation. Could you please accept this new symbol to apply in the next order as it takes a lot of time and money to rework; we also have a concern that the gift box will not be completed after this complicated process. The goods are?? ready to be shipped and catch the vessel xxxx ETD xxx and ETA XXX. We would appreciate if you could consider our suggestion. We are looking forward to your prompt reply.
I've tried this one....but....please ignore it.
(I'm not really sure about the tense...)
