Dear En. Muhammad Abdul,
RE: STATEMENT OF ACCOUNT
I received your letter dated 1 March and the enclosed statement of account. On checking the statement, I found that a debit entry (3 Jan 2009 for the amount USD100) again does not tally with the invoice (no. 1234) you sent me earlier. Your previous statement also contains the same error.
I have already mentioned this to your representative, Mr. Jackson, and he promised to look into the matter. But up to now I have not heard anything from him nor has the error been rectified.
I enclose a copy of your invoice. Please check the account again or send someone over to sort out the problem. Thank you.
