A complaint letter

Dear Sir or Madam:

I am writing to complain about some sneakers I bought last week through your online shop.

The model of sneakers is correct, it is the one  I chose, however the size is wrong. I have bought  this brand several times, and I have never had any problems with the size. But this time, the sneakers do not fit me as well as the previous times. The sneakes are smaller than the size shown. I think that the sneakers have been made incorrectly.

To resolve my problem I would like to exchange the item for another  pair, or if you do not have the same model, I would like to get a refund of my money.

I have bought many  items from your website over the years, and I have never had problems with your online shop so I hope that this situation will be an exception.

I look forward to hearing your news about how to resolve this problem.

Yours faithfully,
