Samsung — Samsung m31 restart issue -motherboard replacement

I have purchased m31 and used it with due care for around 2 years and i am facing frequent restart and hang issue. Earlier i faced this issue in M21 as well. I have reached out to samsung ceo team and customer support, they were ready to bare only 10% of the cost which is just Rs 700. total estimated cost for motherboard repair is 7028 from samsung authorized service center.
For such defect in M series with respect to IC/Motherboard, customer has to pay such huge amount within 2years. You can see in any forum, this issue is common in M series of samsung where they have to replace motherboard in device.
For such poor quality, samsung has to bear the cost of repairing instead of customer paying this cost. Please look into it and ask the management to own the responsibility for their defective
