Data Shock with absurd bill

i was billed for R11,000 for data between 6am and 8am. i have called the call centre and no one can even tell me where there's charges emanate or the ip of the site. the charges are R89 every 3 seconds.<br> i have been messed around and not informed of about the origins of the charges and have not been using my phone in different way. this seems like a big error and i am being given the cold shoulder by vodacom. this is a violation and bullying by a large corporate.
