Cash heist by vodacom after the festive season

Iv had a good relationship with Vodacom until 15/01/19, then they deducted over R1500 from my account, for data useage on a new 1 gig contract. Firstly they conveniently use misleading advertising on their deals like 1Gig data plans, when in fact its an open line. They fail to advertise this clearly, or even call and explain before they close the deal for online purchases.

With this said, We never used r1500 worth of data on the said device as we have other wifi devices which we constantly connect to and mostly use night owl after 12. After the festive season, R1500 is alot of money to just be taken from ur account on something like this , Im appalled, Im horrified. Having 3 other contracts with vodacom and with upgrade time fast approaching note I wont be re-newing as over 3 weeks has passed with constant emails to them, and yet no proper feedback on this issue. The laptop in question says 4 Gig data useage which really does not costs R1500 anyways, tho the laptop was connected to another wifi device and not the one im querying.
