Samsung — LOW QUALITY MOTHERBOARD (Samsung M42)

My Samsung M42 128 8 GB RAM phone is not working it is continuously restarting. I reset my phone to the factory default setting but it still has the same problem. Also, when the phone turns on, I can't able to turn the Wi-Fi on Sometimes its Bluetooth is not turning on. I bought my phone exactly Two years ago, and I also visited nearby Samsung stores they say that it's some motherboard problem and every M and F series of Samsung is facing the same problem also they charge for it too much. The phone costs almost[protected]₹, how can a student pay 10, 000 or 11000+ taxes for some problem that was caused because of the company's low-quality product?
