This example demonstrates what a good letter of complaint should look like. There are notes on the margins. Which indicate paragraphs numbers as explained on pages 26-27. You don’t need to write them in your own letter. It is enough to just leave blank line between the paragraphs
Dear Sir/Madam,
The reason I am writing to you is poor quality of a food processor, which I bought in your store two weeks ago. After only two times it was in use, problems started to appear.
The first malfunction that I noticed was safety lock that demanded applying of great force. My wife had to ask me for help, because she wasn’t strong enough to push the safety lock through. We discovered another problem when tried to use the blender. I put some ice-cream and milk in the blender and pushed the “Start” button. It started working but suddenly got stuck and we were unable to use it since. I was very surprised to discover that much problems in a quite expensive model.
Naturally, I returned the blender to you to be replaced with a new one. Your assistant said that I would have to wait only a week. After two weeks the food processor had still not arrived. Finally, four weeks later, I was contacted by your representative. Imagine my feelings when I learned from him that I cannot receive the same model of food processor as I bought. As a solution he offered that I upgrade my model to a better one and this too will take two weeks.
I am very disappointed with both the equipment and the service have I received. Therefore I expect a full refund of 180$ as soon as possible.
Yours faithfully
Mr. Smith
