Dear Sir or Madam,
I am writing to complain about the jacket which I bought last week in your shop.
I want to express my strong dissatisfaction with this jacket, because I wanted a black colour and a medium size. Unfortunately, when I took it out of the box, I found that there was a red jacket in a small size. I called to your company in this matter but I did not get any interesting answer so I am writing this letter to you.
I would like to change the jacket. If you have not got such colour and the size I demand a full refund of my money.
Nevertheless, I hope you will replace the jacket with the new one. I look forward to hearing from you soon.
