Complaint about your phone, internet or TV provider (CCTS)

Complain to the provider first, then to the Commission for Complaints for Telecom-television Services; time limits and what it handles.

The order to follow

Tell your provider about the problem and give it a reasonable chance to fix it. The CCTS cannot accept a complaint otherwise. Keep dates and the provider's answers.
If it is not resolved, file with the CCTS. The fastest way is its online form; you can also file by email, fax, mail or phone (1-888-221-1687).

Good to know

The CCTS handles contract disputes, billing errors, service delivery problems and credit management. If your complaint is outside its mandate, it refers you elsewhere if it can.
Time limit: the procedural code sets one year from when you first knew, or ought to have known, about the issue (it may extend to 18 months in some cases).
After acceptance, the provider must write back within 20 days to explain its position, according to the current FAQ.
