Dear Sir or Madam,
Thanks for your attention. I’m here writing to complain about your product.
Last month, I bought an MP3 made by your company, which brought me enjoyment for some time. But last week, something went wrong with the screen and I can’t see anything on it. I have talked about this with the shop which sold me this MP3, but they/it couldn’t do anything about it. Having no choice, I turn to you for help. I hope you can get me a new one or return my money to me.
I’m looking forward to your early reply.
