How we can help
If you have a complaint about an outage and can't contact your provider, or you aren't satisfied with their response, contact us.
We send the complaint to your provider and ask them to address your concerns. We ask for a quicker response if you currently can’t access emergency services or if you have other safety or health risks.
You can call us on 1800 062 058 or make a complaint online. You can also contact us using an interpreter, including Auslan or the National Relay Service. If you prefer, you can make a complaint by email fax or post.
