Cell C = Takes money without conscent

I have been with cell c for a few years now already , when i upgraded in November i saw i have something called "Get More" in my contract , I have ever since been trying to cancel this as I do not use it , I don't know what it is and i have been paying for it for over 2 years now. This is ******* . It was aso just added to my account in the 1st place without my conscent , I am still paying after i have requested for it to be removed last year . Please stop *****ing my money every month !!!
