Verboten Vodacom

So, firstly vadacom has been completely off the charts **** for network lately. I know this because I live with someone who shares their router/internet with me. Watching anything has been a nightmare! Secondly, I have no vodacom contract yet someone (from vodacom) tried deducting some money from my penny's, ********ly, with no agreement and no contract signs as well as no authorisation. I am not sure what is going on with Vodacom, if they are going under or being dragged but all of the above is infuriating.
