TELKOM POOR SERVICE AND RECEPTION

I've had a problem with a router I purchased in march 2021 & from September I barely have coverage yet I pay R469 every month. They've sent out technicians 3 times and all 3 technicians say the same thing, the issue is with their tours hence why the router fails to hold network card coverage. So I'm now spending money buying data for my phone as well as paying for this router which is completely useless. Now they refuse that I return the unit and insist on sending me another technician. At this rate I may as well live with the technician cause the problem is consistent. I don't want their router anymore. Their service is very poor just like their network. Infact I will be changing my mobile number as well from Telkom to a different network if this is how they treat their customers/clients.
