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.
