Samsung — Regard my Samsung M30s stuck after updating

Sir, I have purchased Samsung M30s about 1 year ago.And I am happy about the phone.But suddenly last week I had updated my phone, thereafter my phone got stuck at opening logo, can't even use there after.I had send the phone to Service Centre, after the checking they told, it was mother board issue, after the software update, and it cost about 8000 for recover the phone, also they told that it's a manufacturing defect.
As a satisfied customer, this is a bad experience for me, since I had used Samsung phones for last 15 years.
Sir my humble request is pls call back all Samsung M30S phones or provide free instalation of new mother board for the customers.
Pls consider the issue by Samsung India seriously.
Thankyou
