Vodacom are *****ing from their clients!!!

I am completely flabaghasted at the way vodacom is now *****ing money from clients. I received my invoice and notice R 394.93 being charged for VODAFONE LIVE. I have no idea what that is, so I called customer care, only to be told that I subscribe to games and videos at R5 / day. I do NOT subscribe to any type of games/music/videos or anything remotely like that. The extremely rude person on the other side of the phone told me that maybe when I'm on the internet, I may have clicked on a pop up add, which would automatically subscribe me!!!! WHAT A LOT OF BS!! I then asked her how am I supposed to prevent this from happening if it automatically subscribes without my knowledge. I cant keep paying hundreds of extra rands every month. She proceeded to tell me to get a pen and she will instruct me how to check regularly so that I don't phone customer care for the trivial stuff. I am sorry, but I should not have to regularly check my 'subscriptions' for a service that I have not knowingly signed up for. This is nothing more than blatant *****. How many other people are paying extra and not even realising it! Bunch of *******.
