CONTRACTS CANCELLATION

I had two contracts with Vodacom recently ended. I phoned on the 8/02/2021 to cancel both my contracts. Well thought they were canceled as I was not getting airtime, to my surprise when I went to the branch to find out that the contracts has not been cancelled. Was advised by a sales person to phone again the call center, I did call AGAIN 20/04/21 spoke to Mbali from the cancellation department and also spoke to Katlego from Accounts department and they said there was a fault with the cancellation advised will be getting a call from the manager till Today no manager has phoned, this is not how customers should be treated as if I don't want to continue with your service Please Let Go!! This is unacceptable.
