Hi everyone

I have a 2017 switch that has decided it doesn't want to boot up anymore. I've tried a few different things I've found online but I've had no luck so I want to send it in for repair. Mine is out of warranty and I've heard that the official repair center (Core) is garbage anyway, so I'm looking for recommendations for good places to get it repaired (preferably around the Cape Town area, but doesn't have to be).

Any help would be much appreciated.
Thanks
