Request for credit and pickup of merchandise delivered late

The merchandise that we ordered from you on [date], was
delivered on [date], which was [#] days after our sale had
ended. What is most regrettable, is the fact that if we had
the merchandise on hand for the sale, we could have sold
them all.

We understand that you were experiencing some internal
problems during this period. We are, however, unwilling
to keep the merchandise recently delivered, due to the
delay. [Number] cases will suffice for now. We would
appreciate it if you would have someone call for the
remainder and credit our account accordingly.

Thank you for your prompt attention to this matter.

Very truly yours,
