退货英文怎么回复

Dear Sir,While I was on holiday in Hong Kong about a week ago, I bought a green blouse for 268 dollars in your shop, but there seems to be something wrong with it. When it is washed, the color runs. Now I can’t possibly wear it. It’s not my fault, so I’d like you to solve the problem for me. I insist you change it for another one for me or give me my money back. I think it’s better for you to make sure that everything in your shop is good. Then you will have more customers.I’m looking forward to your early reply.Sincerely,Li Hong
