Make a complaint
If you’ve already tried resolving your complaint with your internet or phone provider, you can file a complaint with us. We help residents and small businesses settle disputes fairly.
If you’ve already made a complaint with us, you can update your existing complaint online. This could mean asking for more help, adding new information, or marking it as resolved. You can also track the status of your complaint.
The TIO has a zero-tolerance policy on aggression and violence. We treat everyone with respect, honesty, and courtesy, and ask for the same in return. For more details, please read our Engagement Charter.
