Samsung — Samsung Galaxy M31s motherboard failed after software update

Address: L-11, Shakutal Complex, Adajan Road, Surat. 395009

I purchased a Samsung Galaxy M31s phone in august 2020, After a recent update on 14 July 2022, my phone started freezing and auto-restarting every few minutes. on 15 July 2022, It finally switched off with only the logo visible which is not even letting the device get into the bootloader. I went to a nearby Samsung service centre Shivam Sales, L P Savani Road, Surat. Samsung Service Centre. and they told me that the motherboard needs to be replaced and that will cost Rs. 8000/-.
There were over, at least, 700-800 people with the exact same complaint on the internet and Consumer Complaints forum regarding their phones (all Samsung M-series phones). The update caused the motherboard to fail.
Please, have a look at the disaster the updates have caused. And kindly provide a free motherboard replacement or refund the amount. It's a blunder done by Samsung and expecting customers to pay Rs. 8000 to get the motherboard replaced.
