    Dear Manager,
     Last week I bought at your store and when I got it home it did not work at all. When I tried to return it to the store, I was told that I could not get refunded.
     The sign in your store says that money is returned within 7 days of purchase if any problem exists, and I did that within the said time. Thus I insist that I should have my money back by return the to you store。If I do not receive any satisfying response, I will further complain to the Consumer Protection Association.
     Yours,
     Li Ming
