Fed up

I am on my second month with supersonic and so far I totally regret having changed over from rain. The service is pathetic to say the least. Yesterday I was chatting on Whatsapp it took 3 hours to get a response. I called 3 times requesting a call back which I got at 7pm 4 hours later. Today the same 2 hours and waiting. The issue I have is my router which I got with the package stopped working after only 25 days. There is supposed to be a 12 month warranty but without even looking at it they say it must be replaced for R2500. No attempt to fix it. I cannot afford this so I managed to borrow a huawi b525 router which with no help from supersonic I managed to reconfigure to work. But now for the last 3 days I've had absolutely no internet access. I'm paying R500 for nothing.
