Non Cancellation of a contract after 24months lapsed.

My mother had a cellphone contract with Vodacom and the 24 months has lapsed. Vodacom agents have been calling her and she told them that she wants to cancel it and not do a month to month and also requested an Afrikaans or Setswana speaking agent because she doesn't understand English well. The contract was never cancelled and rather continued on a month to month basis . My brother tried calling and had no joy because of POPI etc. It's extremely bad service to enforce a continued contract on an elder and no one speaking her preferred languages have ever contacted her. I know that it's easy to con elders like this, but I would have hoped that you guys would conduct business in an ethical manner. Her contract number is I***. Initials are KD Pretorius. Her direct cellphone number is ***. Please cancel the contract as she requested and stop debiting her account. The 24 months was over in June already. If there is no tswana or afrikaans speaking agents. Please do contact me on *** and we can do a conference call with my mother to get her consent and canceling that contract. Your services are lacking big time.
