Dear
The shipment of the above referenced merchandise was delivered to my receiving division on While the original delivery date was set for I approved this later delivery in view of the problems that you were experiencing at that time.
Our check for the full amount of the invoice, less our 2% cash discount, was mailed to you on (date).
I am also enclosing a copy of the statement I received today, which includes a charge back for that discount, taken in compliance with your terms. I believe that the source of this error lies in the fact that the date on the invoice was not changed to reflect the delay in delivery.
I would appreciate receiving a corrected statement of my account. Thank you for your cooperation in this matter. Please feel free to contact us for any doubts or clarifications.
