Cancellation of contracts

I have called vodacom cancellation department last year July after my two contracts has expired/ after that I receive the call from the agent saying that they are bringing the phone that I didn't even agreed on they just decided to renew my contract. I spoke to many consultants that they said they are assisting me , until November 2020 the other consultants said it will be the last debit in November. But till to date they are still deducting on my account. April I made a follow up again and the 1st consultants who said all the consultants that where assisting me they never lodged the call bcoz we dnt have ref number and we where given the ref number *** on the 15th April. On the 19th I have received the feedback saying my ref number as per above is now being processed by Gugulethu Khumalo and the service request should be attended to by 22/04/21 she never attended our matter at all. On the 3rd I have called making the follow up bcos they have debited on my account again spoke to Nomthandazo the consultant said will send the email to Gugulethu as she a manager who is accountable for my account to attend to this matter and give me the call on Monday 3rd of which till to date I haven't received anything from vodacom or Gugulethu. I will never make a business with vodacom or recommend it to anyone. What I want to know is there a problem with canceling the two contracts. Hello Peter Please Help me I dnt know what to do with vodacom I just hate it
