Pathetic service

I have had my fibre with Vodacom for a few years. I recently moved in the same complex and had my fibre moved. First the installer came in with a router then a few minutes later came back to change it and gave me a ****py cheap router. Since then I have ridiculous connectivity issues. There is little to no connectivity through the house unless you are near this router. I have logged calls, escalated and it’s been almost 3 weeks and still no call from Vodacom or even a resolution. I also requested they activate my old router seeing I had no issues with it and it is a much better router but no one bothers to get back to me. This is really ridiculous. I am still expected to pay for this stupid service.
