Dear Sir or Madam,
Last week I purchase a UX-15 Underwater Camera from your company, but it turned out to be quite a disappointment. The camera did not perform as promised in the advertisement.
According to your company’s TV commercial, the UX-15 Underwater Camera is designed to take pictures at underwater depths of up to ten feet. However, after using the camera in a swimming pool for twenty minutes at only five feet, I noticed that water had leaked inside it. The film was ruined, along with the camera’s electrical components.
I am returning the camera, along with my sales receipt, in the same package as this letter. I would ask that you issue me a full refund, as I have no interest in receiving a replacement product.
Thank you,
Scott Hyatt What will accompany the letter

A. An underwater photograph
B. The defective product
C. The camera’s original packaging
D. A copy of the sales flyer
