Abysmal Fibre service. Connection has never worked but billing does!!!

I currently have a LTE connection with Mweb. I requested for that to be upgraded to a Fibre connection. Vumatel came through and did the fibre installation. I was then couriered a wireless router. Once I received the router, i did the installation over the phone and it became apparent that there was a fault on the line. Since Feb 19th I have been calling every day or every 2nd day, trying to chase the progress on this fault. Every time I speak to someone, I get the same response that they have escalated the fault and that someone will come out between 24-48 hours to repair the issue. No one has come out to repair the fault and Mweb has not updated me with anything. Furthermore, I received a bill for the fibre account. When I called billing they have told me that since the account is open, I have to pay for this service (which has never worked, and I have to follow up to see why, everyday) and that when the fault is repaired, I will be credited for the down time. Given the fact that I am the one calling Mweb, constantly, to try and get an updated status ( of which the answer is always that it is being escalated), this may take 1,2,3,4 months to get sorted. In that period, I have to pay for a service that I cannot use and has never worked? How does that make any sense? If the line did work and stopped working, i can somewhat understand the billing. But to have to pay for something that has never worked & I am the one who has to constantly call to find out whats going on? This is very frustrating and absolutely disgusting service from Mweb. If this goes on for another week, Mweb can come and remove their installation and I will find another service provider.
