DSTV doesn't care about their customers

I had new explora decoders installed on the 25th June 2020,my secondary decoder is giving me an error E143 since the day of installation.Whenever i call DSTV call centre they promised to escalate and it will be sorted withing 24hrs however to this day nothing has been done. they increased my instalment to r900 instead of r730 which i was told will be my new instalment. they keep promising that they will sort out my issue but so far nothing has changed
