Dear Richard Anderson,
We just received this morning the order we placed last March 2 , and we are really sorry for the mistake. We intended to buy 20 throw-pillow cases, not bolster pillow cases. We regret any trouble or inconvenience your company may have experienced from this. We hope it can still be corrected and for us to receive the items that we wanted. Thank you and we look forward to more transactions with you.
Sincerely,
Oanez
