Misrepresenration by vodacom rewards consultant

Consultant called me daily at least 3 or 4 times to upgrade my contract. After persuasion and having been advised i would be getting a better deal I reluctantly agreed. I was promised that my contract will be emailed and could cancel if not happy which to date it hasn't. I was told that I would receive 10g additional data only to find out today it is a video ticket which I have absolutely no use for. Doing business like this is "rogue deal"
