Dstv sucks

I have spent about 60 minutes on and off the phone with dstv to fix an error E143-0 on the secondary decoder. Every time dstv resets the code and after 10 minutes the error appears again. It seems that dstv does not have the capability of understanding that the error appears again and again, but for a fix, they just reset it again and tell me to monitor. This has been repeated more than 10 times. Obviously they should have a ticketing system and should see that 3 calls have been logged in the time span of 1 hour for the exact same issue. Absolutely rediculous. Dstv is the worst. Rather get a Netflix subscription and forget about the shows you'd watch on dstv. Paying for a xtraview subscription, but only one decoder works
