Poor service

I logged a fault on Friday, when we phoned they said the Saturday afternoon shift will attend to our fault. When no one came, or contacted us, I phoned again and got a very rude call center person. He said they have no turn around on a fault, as the the maintenance department will get to it when they get to it? I asked for that department to contact me as he had zero information to share, and he said he would escalate it! Needless to say, the 48 hrs that I was originally promised by my service provider is about to expire, and absolutely no effort from vumatel! If I don’t phone them, nothing happens
