用英文写一封投诉信

Grandbuy Shopping Mall:
hello!e68a84e799bee5baa6e79fa5e98193335 I bought a colorTV in Grandbuy Shopping Mall on June 10th, but it broke in less than a week and I had called the service center of the shopping mall for help, they replied me that they would contact the producing company to fix the TV as soon as possible. a whole week passed by,no sign shows any one's going to fix the TV up to now,so I would like to return for a full refund.

Dear Mr. Manager,
I’m writing to complain about the poor quality of shoes in your store. One month ago I bought a pair of shoes from your store. It wears well as I like.However, it was broken in less than a month. It disappointed me much.
I choose to complain to you because I’m sure you will be able to take back the shoes and pay an indemnity.
Yours faithfully
Tom
