Unknown Subscription, Data Usage amount

<p>Vodacom agai n!!!! I am so tired of reporting Vodacom, but it seems that they bill you according to how they see fit. My number has been subscribed to 3 or 4 different VC's without my permission, Vodacom cannot tell me who authorized this?? I'm on the Red advantage package, and I have set a limit of R 1 000.00 for my data but each month my data is over that limit without my aurthorisation. I do not understand how this system works?? I get a sms to tell me my data is depleted, so then I buy data from my phone which costs me roughly R 452.00. What I don't understand is that if my data is depleted and I buy an additional data, where does the data usage of over R 2 000.00 come from? Sufficient and clear answers are needed urgently!!</p>
