Terrible service from VODACOM

I’ve been trying to cancel my VODACOM contract for months now without any success. First of all VODACOM is not debiting my account as per our initial contract, and they can’t explain why. The only thing I get is I’m always in arrears cause of their incompetence. I then requested a cancellation quote which I received and paid in full but when I call them the account is still active and they tell me I did not pay the full amount. I request a second cancellation quote which I was told I need to settle within 7days and I did but to my supplies the contract isn’t cancelled and I’m still owing money that I don’t where it comes from. Worse part is when you call their contact center they will put you on hold forever but they still can’t assist you. I’m really sick and tired of this service from hell.
