Cancel CenturyLink - step by step
CenturyLink often does not prorate the final bill

Unlike some providers, CenturyLink may charge you for the entire final month regardless of when you cancel. Cancel as close to the end of your billing cycle as possible to get full value.

CenturyLink, Brightspeed, and Quantum Fiber - which one bills you?

CenturyLink has split its consumer business. In many states, copper/DSL service was sold to Brightspeed, while fiber service is branded Quantum Fiber. Check your bill to see which entity charges you, as the cancellation phone number and process differ. The general CenturyLink line is 1-800-244-1111.

If CenturyLink keeps billing after cancellation

File an FCC complaint at fcc.gov/complaints for any billing that continues after a confirmed cancellation. Dispute the charge with your bank using your written cancellation confirmation. The FCC complaint forces a formal response and resolves most disputes.
