Dear manager,

I am writing to tell you something that happened on me in your department store the other day . I came there to buy a shirt. I chose one and paid it. However, when I got to home with it, I found the front part and the back were of different colour. At once I went back to your store and hoping that I could have it change. Unlucky, the shop assistant refused to do that for me. She said that I must have chosen it more carefully. Now that I can only do is to write you for help. I believe you will try your best to settle the problem.
