Package that don't exist, billed for internet that I don't have and very poor customer service

App**** for a package from webafrica, they cancelled the package and moved me to a more expensive package without informing me. I tried to get help throught their whatapp infromation help center but they keep on transferring me to a new person. So far I spoke to Melissa, Layaan, Mmbatho, Courtney,Dino, Sfiso, Sinethemba and Fiaza. I tried to call them to sort it out but they just say they system is slow they will call me back. So I tried to move my package to a different promotional package because i'm still a new client but they apparently can't do it because it's only for new client (I dont even have a router yet). I received a bill for the internet I don't have and the already debited my account account as well for internet I don't have and when I query them about it they say they see I have used some data from the internet I dont have yet.
