Unauthorized contract renewal at plummeting costs at Vodacom

On the 25th August I got nasty surprise as I was charged an inflated amount of R686 as opposed to the usual amount of R386 for my Vodacom contract. When I went to find answers at the Benoni Lakeside mall Vodacom shop I was referred to the call centre for answers. After being send from pillar to post I was told that I had been upgraded. What is even more bazaar is the fact that I was upgraded but with no added benefits what so ever. This is **************** on the part of Vodacom and its sales staff who called me in June andtold me a story about how Vodacom appreciates my business and would like to keep my business. They ( VODACOM ) are going to decrease my monthly contract costs and soon I will be paying a significantly reduced price. This has turned out to be nothing but a hoax and a ****. I want my money back Vodacom !!!!!
