The error code that DStv employees and accreditation installers can't clear.

I paid R830 on the 1st of September for my DStv compact extra view. There is an error on my other decor and t I tried to clear it through their app, WhatsApp, Facebook and I even called them and I was assisted on the 1st and it worked until Saturday around 21:00,on Sunday it still didn't work, Monday I tried to clear the error through the above mentioned platforms without luck,I took the decoders for testing as they suggested and they were declared to be fine,then came back home the TV played after a few hours the error code appeared again and I called and told the guy who was assistin what the problem was and he managed to clear the error but fifteen minutes later it appeared again and I immediately called back and the lady said she'll get someone to call me back,I'm still for the call. I paid DStv to watch the error code,I'm using my own money to get help from them,I paid an installer for nothing.I don't think I'll ever pay DStv again it's so frustrating.
