******** contract I can't cancel

I got an Sms from Edgars around 2014/5, it stated that I could get a R60 airtime for only R20 or so extra on my instalment, this sounded like a good deal and I opted in, but I later realised that this was a contract as I lost all my Vodacom talking points. I then called Edgars and got this cancelled. But the airtime kept on coming, I have since cancelled the Edgars account but the airtime still keeps coming. The big issue came when I needed to port my number and I couldn't because of the supposed contract. Vodacom also says that they cannot help and this RMCS place has wrong numbers on their website that go through to natural persons and when the Vodacom call centre puts you through to them you wait for over 10 minutes and then the line goes dead.
