High bill due to so called "content Services"

Since August my bill went from R745 all of a sudden to R1000. Did an enquiry at Vodacom Centurion mall (must say the worst service EVERY - Manager of the day - Sashin), I was told that I accidentally activated Uchater. I DON'T EVEN KNOW WHAT IT IS, and how can you accidentally activate something you have to pay for. I then requested them to immediately deactivate the service. After promising me that it was deactivated, I decided to go to the Vodacom website to see if it was deactivated. After searching for hours to find the service I eventually found it hidden behind a button that says Mobile content services just find out that THEY HAVE NEVER DEACTIVATED THE SERVICE AS REQUESTED AND PROMISED!!! After being a customer from the day I bought my first mobile phone I THINK IT IS TIME NOW TO MOVE TO A NEW SERVICE PROVIDER.
