I am sorry that you have not yet received my payment this month. I recently found an error in my account and didn't want to send the payment until I was sure that check would not be returned. The bank has since accepted responsibility for the error, and I plan to have the funds transferred to you immediately.

The bank has assured me that the circumstances that led to the oversight are unusual and it is unlikely that this will ever happen again. I have been happy with our business relationship and trust that this incident will not jeopardize our future dealings.
