How to complain about Telstra

Work through the stages in order. Each one creates the paper trail the next stage needs.

  1. 1

    Stage 1

    Complain to Telstra and get a reference

    Straight away

    Contact Telstra and ask for a formal complaint. Record the reference number, the agent's name and what you were promised. Ask for the outcome in writing.

    Use the phone, chat or complaint form on this page.

    Ask for the provider's complaint policy and the expected response time.

  2. 2

    Stage 2

    Allow 10 working days

    10–20 working days

    Give the provider 10 working days to resolve the issue, or 20 working days for a complex matter. If it refuses to help or closes the complaint, you can go to the TIO sooner.

    Follow up in writing and keep the final response.

    Write down the date you first complained; the TIO will ask for it.

  3. 3

    Stage 3

    Take it to the TIO

    Generally within six years, but act quickly

    The Telecommunications Industry Ombudsman is free and independent. It can investigate, conciliate and decide remedies.

    Submit the complaint online with your reference number and evidence.

    State the outcome you want and attach the provider's final response.

  4. 4

    Stage 4

    Report systemic issues to the ACMA

    Any time

    The ACMA can investigate industry-wide or repeated breaches of telecom rules. It does not resolve individual disputes or award compensation.

    Use the ACMA's complaint and reporting information after the TIO stage.

    Reference the specific code or rule you believe was breached.

Questions

Telstra FAQ

How do I complain to Telstra and escalate to the TIO?

Call 13 22 00 and ask for a formal complaint reference. Give Telstra 10 working days to resolve it. If it is still unresolved, contact the TIO, which is free and independent.

Can I keep my number when I leave Telstra?

Yes. Ask for your account number and transfer authorisation, then give them to the new provider. Do not cancel the Telstra service until the port is complete.

When can I contact the TIO?

Usually after you have complained to your provider and waited 10 working days (or 20 for complex issues). You can contact the TIO sooner if the provider refuses to help or has closed the complaint.

Does the TIO cost anything?

No. The TIO is free for consumers and small businesses. It can investigate the complaint and, where appropriate, order remedies including compensation.

Can I contact the TIO immediately?

Usually no. Give the provider a chance to resolve the complaint first. The TIO generally expects about 10 business days for a response, but it can take the case sooner if the provider refuses to help or closes the complaint without a resolution.
