Vumatel - No connection for over a week! No Resolution!

I've moved to a new premises over a week ago and found the existing fiber ONT device disconnected. I've had to jump through hoops with my ISP (Webafrica) and explain the same thing over and over to several agents. A ticket was eventually logged to Vumatel (***0). The technicians came days ago, had a look around and left, saying another team will have to re-install the ONT. I haven't heard anything since, but the ticket was closed as "Resolved"?? I simply need the ONT to be reconnected which should be less that an hours work, but I'm waiting for over a week and I'm told it could be another 3-5 working days! This is a critical impediment for me as I cannot work without an internet connection. This is unacceptable service delivery that I am paying for!!!
