Complain to the Telecommunications Ombudsman

The Telecommunication Industry Ombudsman (TIO) is an independent organisation. Their role is to sort out telephone complaints and disputes, quickly and fairly. This is a free service.

When to contact the TIO

If you have a problem with your phone or network, you must complain to your telco first. 

The TIO should be your last resort, if you are not happy with the result from your telco.

When you contact the TIO, you will need to tell them:

  • what the complaint is about
  • the name of the telco and the account number
  • if you are the account holder, or you have their approval to make the complaint.

You will be asked for the complaint reference number your telco gave you – this is why you need to complain to your telco first.
