Dear Customer Service Representative,
I am writing to comp[ain about the bad delivery service of your company.
The IBM Desktop computer we ordered from your store two weeks ago finally arrived yesterday. There were not any signs of damage to the packing case at all, but when we opened it, we found, much to our surprise, that the back cover had been cracked and the screen had been scratched.
In view of this, I have decided to make a formal complaint against your delivery service. I sincerely hope that you will replace this computer as soon as possible. If this is not possible, I will have no alternative but to insist on a full refund.
I would appreciate anything you can do to help us in this matter.
Yours truly,
(Signature)
