Vodacom Online Department is Useless

After upgrading my phone via the online department, I waited for my phone to arrive. I was delivered a sim card in August to be told to wait two weeks later for the phone to arrive. Nothing. I called them they said there's no phone upgrade registered and they need to collect the sim card in order to cancel it. It is now 30th November. I've been told they will cancel the contract by today and I'm still being debited. The service is shocking, I'm paying for something I don't want and no one is listening
