Vodacom contract cancellation / Theft.

I have an LTE contract which I was trying to cancel, well ahead of time to make sure that they cancel it after the 2 x year period. Every time I wanted to cancel, Vodacom told me that I should phone 2 x weeks before the last Month of the contract after which they will then cancel it. I did as they asked and phoned again 2 x weeks prior to the contract auto-renewing and asked for it to be cancelled. I was told that it will be cancelled and received 1 x sms stating that it will only be completely be cancelled when I receive further sms's. For 2 x months leading up to the expiry date, I was contacted numerous times by Vodacom and their suppliers, trying to convince me to keep it on as a data package. Every time I declined, stating I have Vodacom Fibre, and a Cell phone contract (For the last 22 x years)and I did not need the LTE package anymore. Nothing happened and low and behold I was billed for yet another Month after the expiration date. Again I phoned Vodacom to have it cancelled, after which I then received sms's stating it was cancelled etc. I asked the lady to please get back to me on how they are going to pay me back the additional Month, after which she said they will contact me. Vodacom has not contacted me, and after also sending 3 x emails to customer care, nobody has contacted me yet. Nice, ***** R999.00 from your "x" million customers and you have yourself a great bonus payout.
