Service as slow as their internet connection

I write this review as all methods to contact Supersonic has failed. Been with Supersonic since beginning 2019 and had no issues. Starting 2021 the network started dropping download speeds as low as 0.09mb/s on a 20mb/s line. After reporting the issue, I waited several days before they call back and they always"working on the problem" but they never seem to solve it. Last week same problem, only now they claim it could be the router as they had several complaints regarding these routers as it is cheap products they use for "free" installation packages. Today the tech guy was here and tested the router and said the router is faulty and a replacement will cost me R1000. Well here is my solution Supersonic, I will change over to another service provider that will do free installation and a free router and hopefully with better service and will safe me R1000 and the frustration of dealing with Supersonic again.
