What is a Complaint Letter?

A complaint letter is a formal letter. That means it is not like a friendly letter to your best friend.

You write it to someone like a shopkeeper, company, teacher, or principal to talk about a problem.

The goal of a complaint letter is to:

  • Share your problem clearly

  • Be polite and respectful

  • Ask for a solution

You should always stay calm and use good words. Even if you are upset, your letter should not be rude.

Why Do We Write Complaint Letters?

There are many times when you might want to write a complaint letter. Here are a few reasons:

  • When you buy something and it is broken or damaged

  • When someone does not give good service

  • When there is too much noise or litter in your area

  • When something in school is not working properly

  • When a delivery is late or missing

Writing a complaint letter helps solve the problem. It also shows that you are responsible and know how to speak up in a nice way.
