So frustrated with HomeConnect

So it's almost a week now without internet access. Vuma Tel came on Saturday morning to install the white fibre box. The technician on site said his part is done that's the hardware installation and their office will activate our line that will take 1-2hrs. They left here around 09:35. I spoke to home connect this morning just after 07:00 and Hendrieta said that Vuma Tel did not complete their installation part which is to install and activate. Now we can't get a hold of home connect telephonically. We are left on hold from our cellphones. Their last message is that we must wait for (24-72 working hours) which is 3days - 2 weeks for them to get a technician to come here. The technician already came, why must we wait again because of their markup? It's not our fault, it's their mess that is costing us
