Dear Sir, I (1) am  writing to complain about EASY camera. I bought (2) it two weeks ago. I just received my first set (3) of color photos only yesterday. I am enclosing them with this letter. You will see that they (4) are  very dark.I think that your EASY (5) camera is very bad, but I will try again. You see, (6) it wasted my money on (7) my first set of photos. Would (8) you please send a new film to me? If the next photos are also very (9) bad, I will send the camera to you and ask you (10) to return my money.
