Samsung — Samsung M31s Mobile motherboard

I purchased a Samsung Galaxy M31s phone about 1.1 years back, on 27th Aug 2020 from amazon . After a recent OS update (security patch update), my phone started freezing and turning On now. I went to a nearby Samsung service center (Samsung Service Centre Rajapalayam) and they told me that the motherboard needs to be replaced. There were over, at least, 10 people with the exact same complaint in the service center regrading their phones (all Samsung M-series phones). The update caused the motherboard to fail, and of course it was never mentioned by Samsung that "Hey, this update might make your phone completely unusable, so update at your own risk!" and now they're expecting us to pay Rs. 8/9k for the motherboard replacement? Shouldn't Samsung take responsibility for this huge blunder that they've created, causing a loss of both time and money of thousands of its trusted users?

Thousands of M30s / M-series users are facing the same issue, and there's not a single word from Samsung other than "Send error report through their Samsung Members app" ! How is someone supposed to do that when the phone keeps restarting and it's already declared a hardware fault caused by an update? Is this what a brand is for?

Please, have a look at the disaster the updates have caused. And kindly provide a free motherboard replacement or refund the amount, caused by your updates or its going to social media, and will definitely file a case.
