Today, I took you for giving me the letter of credit to the bank, bank staff told this is only a single letter of credit of grass, but not really letter of credit. If you are out December 3rd letter of credit, then we could be December 7 received. But now we have not received your letter of credit. So, I ask what you trouble the bank, ask whether they have given us out of the letter of credit (in the opening letters of credit before the bank will print out the grass alone, but it does not mean it has given us out letters of credit). If the banks do not open out, then please amend the wording of the letter of credit by the way the latest deadline.

Today I went to the bank with the L/C offered by you,the bank staff told me that what you offered me was not a L/C but a draft .If you can open that L/C on 3rd December, we can get it on 7th, december.But now we do not get your L/C yet. So please ask the bank in your side if they opened the L/C(we know that draft could be offered before an official L/C, so this doesn't mean you have opened a L/C). If the bank did not open it, please modify the item of the EXPIRY DATE.
