Vodafone Live unauthorised charges

I am now sick and tired of Vodacom being too big to care about anyone but themselves. I feel like blood vessels want to pop every time I must deal with them. This new problem I am having is being charged every month for Vodacom Live and I have not requested it or authorised the fee. I dont even know what it is. Where in their right mind does Vodacom think they can just add on a fee for some *******. I would like to get back all my money that has been charged over the last couple of years for this service. Please can Vodacom show me where I signed or where they told me I would be charged for something I do not use. This is absolutely outrageous and i will not tolerate it. Could somebody with authority please contact me and not palm me off to yet another 'Help' desk.
