PlayStation Sold Me a Defective Product and Warranty Isn’t Valid In Turkey

I bought my PlayStation 5 from Wehkamp in the Netherlands and when I first unboxed it and turned it on, it turned itself off and then when I tried to turn it on, it didn't work. The socket I plugged it into was surge-protected and the internet and smart TV were plugged into the same socket, there was no interruption or fluctuation. I changed the cable and socket but it still doesn't work and I'm abroad (I'll be in Turkey for 3 months) and they said the warranty isn't valid here. I experienced such a grievance as soon as I unboxed a product I bought brand new. Please help.
