Horrific service

I bought a decoder at PEP (4419) Johannesburg on the 6/1/2022. The decoder has a 1 year warranty. It got hit by lightning last week when there were heavy rains. It is not switching on. I called DSTV, they don't know who needs to be accountable, called PEP, they also don't know. How ridiculous. I want answers!!! The closest PEP to me is Protea Glen Mall, I can't go to either a PEP or Multichoice centre trying my luck. When the agreement with both parties was made, they should have agreed who will service the customer.
