False and misleading contract information!

I was phoned on the 30th of Aug by Vodacom Online Upgrades. I was informed that my contract will expire and I can upgrade. The lady ran me the details down of what the contract entails. I even repeated the details since I wanted to make sure I will get the 2G data free every month. She said yes. On the 2nd of Sept I checked on the Vodacom app and there was nothing of that 2G data. I phoned on the 4th of Sept and spoke to Pumi, She said she will have to take it up with Management and they will have to listen to the recordings. It is now the 18th and I have not heard anything back from them. I phoned again today and they say they have to take it up with management. Now I am past my 14 days to cancel and still no answers. This is the second time Vodacom has disappointed me with their Online Sales. They give false information and you have no proof of what was promised. BAD BAD BAD SERVICE!
