******** deduction of money

Another R270 disappearing into thin air (no wait, sorry, for Content - Vodafone Live, whatever that may be). Every now and again my airtime starts disappearing. I have now learnt to send an sms (which I have to pay for) to stop whatever **** Vodacom has decided I want to subscribe to, but lo and behold, not 100 years later, there the airtime goes again. Please refund all and any moneys that have to date been deducted from my account for this...service? content? whatever it is, I don't even know!!!!!!
