Dear Mr. Lee,
I wish to point out an error in the statement that I received from your bank yesterday.
According to the statement, item No.12 shows a credit entry of USD480 cash on 01 May 2xxx. My clerk said that the entry should be USD500 instead and she showed me the cash deposit voucher to prove it. Perhaps an error has occurred somewhere along the line? I hereby enclose a copy of the voucher for your perusal. Could you please look into the matter and make the necessary correction?
