I cancelled my service 7/31/26. I was paid up to 8/13/26. On 8/10/26 I was notified that I would be billed on 8/13/26 for service from 8/13/26-9/13/26 as Centurylink does not give prorated refunds. I am tempted to call my bank and challenge the 8/13/26 charge but as it is only $55, it probably is not worth my time. I cancelled my service which was 1 internet line up to 40 mbps, actually was 25 mbps on multiple l tests. Also over the 7/4/26 the internet was down, and they couldn't be bothered to repair the problem until after the holiday weekend. Starlink same charge and a real 100 mbps.
Recommendation: Don't expect Centurylink to value customers and expect predatory billing.
