Vodacom Server Connectivity Problems and NO ONE knows how to solve it

I have tried 1 x shop to undo a incoming call barring and they could not assist. I tried Vodacom online and they could not assist. Just a response from a technician saying I downloaded an App that is barring my incoming and outgoing calls. No such App downloaded. Did a Sim swop and still will not unbar calls. Saying its a problem connecting to the server. I've tried all possible combinations of passwords and nothing will unbar the call barring. I did a factory reset and still cannot make or receive calls on the Vodacom network. I am fed up and I am now going to look at approaching CONSUMER PROTECTION or lodge a Civil Case, as I have a phone that I am paying for which CANNOT make or receive calls.
