英文写投诉信

Dear Mister:

As one of your customer, I have recently experienced some problems with the quality of the cell phone SQ200 sold in your store.

Not only have I noticed that the camera function can not be achieved but also in the text service I found it fails to send or receive messages.

As the result of this, I would like to request for returning or at least exchanging this cell phone.

I trust you will give this matter your immediately attention and duly handle it.

I am looking forward to your response.

Sincerely

Wang Hua
