What is a service complaint letter?

A service complaint letter is a formal written document used to raise concerns about problems or issues with the services rendered under B2B and B2C contracts across Australia. The document is governed by Australian consumer laws, as well as relevant state and territory regulations.

The parties involved in this sample for complaint letter are the client, also known as the customer, and the service provider. The client is a person or company filing the complaint, while the service provider is the recipient of the complaint letter.

The text of the letter clearly sets out details of the services provided, issues, specific requested outcomes (for instance, a refund or repair), and identification details of both parties.

Compensation

Australian consumer law provides a list of compensatory measures for the sender:

Further Actions
