Vodacom *****ing From Customers

BEWARE: "VODACOM" Billing Issues... I took my phone in to be looked at because my wifi doesn't connect. This was on the 29th April. I collected my phone yesterday 5th May (I had my sim with me the entire time the phone was away and I never inserted it into any devices) and after a couple hours my phone gets locked and I'm told by Vodacom that I have used R4100 worth of data. So they're saying that from 1 May 2016 to 5 May 2016 I have apparently used this data without being in possession of my phone and without my SIM card being in any devices. After numerous phone calls not one representative has called me to explain what is happening, then this afternoon I get an sms to let me know that now my data usage is up to R4800. PLEASE SHARE THIS TO EVERY GROUP IN SA because the country needs to see and be made aware of how these companies are taking advantage of us. Any legal advice would be greatly appreciated because I will NOT back down.
