Vodacom automatic subscriptions

Once again it's myself and vodacom. My question is: Is vodacom getting a kick back for these subscriptions? As they are the only service provider with this problem. After all the wasp subscriptions has been sorted on my mothers phone, I get a rediculously high account from vodacom this month. Apparently my tablet on the contract is now subscribed to vodafone live for gaming content. Is this not funny as this tablet gets rarely used. Maybe every second weekend or so. After quering this I have been told it can only be unprotected apps/services. I have every possible protection on this tablet you can think off. Note I have not agreed or authorised any such subcriptions. Have also not clicked an ok button. Now you as vodacom wants me to believe that a pop up or add can change and authorise a subcription with out human intervention. Really how darft do think people are. My action will be not to pay vodacom until this has been sorted in the promised time frame of 7 days. If vodacom has a problem with this they can send a courier on their account fetch my phone and tablet, also cancel the contract with out any further payment. Sure MTN or Cell C would be happy to have a new customer.
