DSTV BAD SERVICE!!!!

I got my internet router from DSTV last week Tuesday, concluded the contract via phone quick and easy. I was told to Rica my simcard as soon I got the router and I did that on Tuesday night with an agent on WhatsApp and was told to wait 24hours. Wednesday an agent I called said I should pay the pro rata and the internet will connect as the sim is Rica'd. Thursday I did a follow up on the phone and WhatsApp and they kept telling me to wait and 30 minutes, some would say an hour but still the internet did not connect. Friday I made a follow up again in the morning was told to wait 24hours again, during the day I called was told to wait 30 minutes. Friday night I called again and only then I was told my sim has a problem. at this point I had spend more airtime then the pro rata amount because they do not call you back and on WhatsApp the agents end the chat when they feel they had enough. I made follow ups on Saturday and Sunday, I was told the escalations department works days. Monday I followed up again, I was told to wait 48hours. the next Tuesday which was the 11th of Feb, I requested cancellation I was told of fee of R1660, why would I pay a fee for bad service? I honestly wanted their internet but now I am TIRED of the agents of their lies and deceit. Today just 30 minutes ago I was chatting to and agent, also said I should wait 24-48hours and logged off. I emailed DSTV and I haven't had response from that as well. At this point I am raged and furious.
