Vodacom commits *****

I have been a loyal customer of Vodacom for 14 years. In November 2020 I canceled my three contracts with Vodacom due to getting a better deal from another service provider. Vodacom continued to debit my bank account even though I had no contract with them this happened from December 2020 until June 2021. I made numerous calls to Vodacom from my Telkom number wasting my own airtime speaking to numerous Vodacom consultants including managers. I was promised a refund from December 2020 to June 2021 but to date I do not receive it. Finally a consultant assisted me and the debit stopped as I threatened to go to hello Peter. The debits started again from December 2021, what am I being debited for when I do not have any contracts with Vodacom? Is that not *****? I would like a full refund of all the money that was debited from my bank account from November 2020 to date. Vodacom consultants and managers lie to their customers and commits theft by charging customers for services they do not have.
