Vodacom Insane Data Charge

Vodacom notified me today (2015/04/28) via SMS that there is unusually high data usage on my phone.<br> Unusually high indeed! My bill is apparently R 8,581.31 already! <br> <br> I phoned customer support to enquire where this data usage is coming from, and the lady told me it happened on 2015/04/25 and that there is no mistake on their side - her \proof"of this is an \""itemised bill\"" which simply gives an \""Access Point Description as lte.vodascom.za\"". In any case"
