Vodacom

I have been supplying the ********* that broke into our house with 10G data per month for the last few years because of Vodacom's inability to assist me with canceling my data contract, that expired years ago, for the severalth time. Just when I thought I finally made a breakthrough and canceled my contract (which I'm not sure whether I succeeded in at all now), they added extra costs to my bill? This is not the way to do business.
