Samsung — Manufacturing defect product

Address:

Samsung Opera House

Purchased Samsung M51 on Oct2020. In a span of two months the phone started throwing tantrums such. On several occasions the ohone stops charging ams abruptly starts charging.
Took it to Samsung Opera House, Bangalore, they said maybe dust accumulation and fixed it without registering a complaint.
Same episode repeats 3 months later and exercise repeats. Go to service centre fixes in 10 mins and i come back with the device.
Now the issue has worsened. Phone hangs, restarts and goes on loop with only Samsung logo appearing at boot.
1 month past warranty date and I take it to service centre. I made sure to get a complaint registered.
Service request - [protected]
They claim that mother board has to be replaced for which I'm definitely not going to pay 11000₹.
Paid 27000₹ for the device. Within 13 months mother board replacement is ridiculous for a factory faulty piece.
I will not stop untill I get a fix for this.
