MWEB in breach of providing a service but continue to debit our accounts even after we cancelled in May already

So we cancelled this facility in May 2020. My contract clearly stated that this is a month to month contract. Requested for our voicecontract several times to deaf ears.

Today I noticed that mweb have continued to debit my account after my cancellation of a service they did not provide and is in breach of. WHY SHOULD I PAY FOR A SERVICE THAT DID NOT WORK. THEIR TECHS WAS OUT WE AGREED WE DONT WANT THIS AND REQUESTED IT BE CANCELLED. Surely you stop billing immediatley when you are in breach of providing a service. You have debited my account repeatedly during a really strenious time of covid...
