Dear manager,
I'm one of your customer. The day before yesterday I bought a walkman in your shop. Before I left,
I'do check it carefully and everything was all right. When I got home, therefore, I found a fault with it.
The problem is the "Play" doesn't work at all. Probably it's not your fault and so is mine. Anyhow, I can't
solve the problem on person.
You see, a walkman is of great useful for me to learn English and I cannot wait for too long before
this problem is solved. Hopefully you will deal with the walkman without delay, when you accept my letter.
Hoping to hear of you in the earliest possible time!
Yours sincerely,
Li Hua
