Dear Manager,
Now I am writing to tell you that I boug your shop several days ago. But when I brouge and turned it on, I found it didn’t work properly. So I took it back to the shop and told the assistant what had happened. To my surprise, your assistant didn’t help me to solve the problem. On the contrary, he shouted at me rudely and refused to examine it.
I know that your shop enjoys a high reputation of good service, so I bougers.
I hope you will look into the matter and give me a reasonable explanation. I am waiting to know how you will deal with it. Thank you for your consideration and I am expecting an early reply.
Sincerely yours,
