Fed up with Vodacom!

I have tried to cancel 3 numbers, and have tried numerous times. But every time there is a different excuse. Then they say it is only due for an upgrade, I can cancel in 2 months. When I phone in 2 months, then they say no the contract is only expiring in 2 years. How is it possible for Vodacom to renew a contract without permission. That is why I am sceptical to answer the +-10 Vodacom calls a day. They have even added data to my daughters number, which is also on my name, without my consent. At this stage I feel like leaving Vodacom and getting a different subscriber, because it is *****, how they are handling contracts. And nothing can be done anymore in person, everything over the phone, and that is why there are so many mistakes. And we don't write the names of the consultants down when we talk to them. The lady who phoned me today said she is contacting me in connection with the 066 number that is due for an upgrade. When I said no I want to cancel, then she said no it is only due for cancellation in 2025. How can she say in one sentence it is due for an upgrade and after I say cancel, she changes her story!. I am fed up with Vodacom, after I have been a loyal customer for over 20 years, with 6 contracts currently on my name! This is unacceptable
