Vodacom ********* business practice

I have a cellphone contract with Vodacom. One Vodacom agent calls me and advice that I changed my price plan. The price plan he was proposing sounded good and beneficial to me. I repeatedly asked if it won’t affect my present monthly payment and he constantly maintain that the amount I’m paying will not increase. He also explained that if I want to go back to my old plan I can do that anytime at no cost. Fast forward to the future my monthly installment has tripled. I call Vodacom now I’m told I have to stay with new package for at least three months. These completely something I was not informed about. I believe this is misrepresentation of information to innocent clients actually it’s a **************** from Vodacom. I’m trying to get hold of ICASA because I believe they should also intervene as this practice is ********* and unjust to the majority of unsuspecting clients. I do not think I will ever continue with Vodacom, companies with these kind of practices should be banned.
