Horrible experience alleged contract with Telkom

Since 2016 I have been fighting with Telkom on a fictitious sbd ********** contract they allege I have with them . I have on numerous occasions proved to them that I do not have any of their product and I reported their abuse of my bank account to PASA. They were requested to send the contract together with the mandate I signed that entitled them to debit my account but they failed but continued to debit my account until I blocked them. When they realized I did this , they resorted to blacklisting my name without legal grounds. Whilst I intend to challenge them separately on this , I intend to also publicize the communication between my bank and them where they could not submit a mandate regarding the alleged contract . They used an old contract that I had and that had expired. This company does not only lack customer service , it lacks regard for the law in general as they go against the consumer protection act and other requirements. The PASA complaint is still open therefore they were not entitled to list me before all dispute processes were concluded.
