Webafrica cancelation of service

I cancelled my service with webafrica on the 8th of November 2022 and on the 1st of January 2023 I received an email from them saying my cancelation is complete, but when I go to metrofibre to activate my line webafrica does not want to release the line, so I can't switch to another service provider yet. I tried calling them but they hang up the phone as soon as they hear your problem, whatsup chat is not answered as well, when they answer they tell me the service is cancelled on their side. Webafrica is the worst service provider.
