Dear Mr. Roger Wilson:
I am sorry to notify you that your company obviously has sent the wrong paper to us this morning. As currently, our company does have an urgent new project from our valued customer. I need to receive a new and correct shipment before June 5 or I won't be able to complete the project in time. I may risk of losing this important customer.
Looking forward to your reply.
Sincerely yours.
