Ash has a problem with his phone bill. What does he need to do before asking the TIO for help? And how does he make a complaint?
Make a complaint
If you’ve already tried to resolve your phone or internet complaints with your provider, you can make a complaint with us. Our process helps support residents and small businesses to settle disputes fairly.
If you have not tried to resolve your complaint with your provider, you can find their contact details by searching our providers list.
The Telecommunications Industry Ombudsman (TIO) acknowledges that sometimes emotions can heighten. Your concerns are important and we will support you while you are involved in a complaint, however, we expect that you will be respectful and courteous to our people.
TIO has a zero-tolerance policy on aggression and violence towards its employees. Our people work hard to support you and have the right to a safe workplace free from abuse, aggression and violence.
