DSTV Signal Strength issue not resolved????

My Explora was working 100% on Saturday (3 January). We had a severe hailstorm and then it indicated No Signal. We checked and saw that the LNB had damage. We bought a replacement unit (as we have dual view) for over R850. We replaced the LNB. Thereafter, 85% of the channels are not working. I contacted DSTV today (via the Chatbot) ... after nearly an hour of back & forth, I was informed to contact an accredited installer as my Signal Strength & Quality must be over 85%? Why is it working on some channels (101, 155, 202, most of the kids channels & the news channels). I told the consultant that my monthly premium is R1200, then the R850 for the LNB. An accredited installer will cost over R1000 (call out). So, DSTV is costing me over R3000. For something that was working 100% fine 3 days ago? No wonder DSTV is losing customers by the heaps on a monthly basis. Continuous additional benefits for the lower packages, but nothing more for Premium customers? Seems like the Canal+ takeover did not really change anything. Streaming platforms are sounding like a MUCH better option.
