DATA USAGE of R1 000!

I received my itemized billing showing a daily breakdown of my calls, data and SMS usage. On the data, each date the charge is R0. However, on 1 June it shows I've used R1000 worth of data. This is impossible. I've phoned the Call Centre and the Consultant agreed that it looks wrong and opened an inquiry for me. S3-8ACID-DVQOB. I was told 48 working hours for feedback. No surprise, no feedback. I phoned again today, and the Consultant said my query is still pending. <br> I receive SMSes from Vodacom to inform me of my data
