Vodacom Data disappeared and charged for!

<p>Being a client of Vodacom for 24years I have never had an astronomical data bill - I know how all works. Last month I received a bill for over R3000.00 Rand - and the next week at the beginning of the new month - September - got notification to say that my data was depleted ! Impossible . I have logged a complaint - needless to say have still heard nothing - I absolutely refuse to pay this ! Reference number 1- ********** 2402</p>
