Vodacom *****ing from me. And not taking accountability.

I am so frustrated, canceled my contract with Vodacom October 2023, To date they still debit my account. In store they say I do not have any contract with them, called ***, They say my number is invalid yet they still debit my account. On top of that, when I load airtime on that same simcard, it gets chowef before i can even use it. And I don't understand why would the law agree to cellphone networks to subscribe us with contents we know nothing about and never agreed to. This is self seriously not fair. Shuu, i need help imaging losing an opportunity because of R100 debit order.
