OnePlus India — OnePlus 8T - Faulty Motherboard

I purchased OnePlus 8T in Feb'2021 through Amazon. Recently the phone just switched off while I was about to call someone. I reported the issue at the nearest Oneplus service center in Brodipet, Guntur on 6 Jun 2022. I understand that the motherboard is dead and since the product is out of warranty, the new motherboard replacement cost is almost equal to a new Oneplus 8T mobile.

I feel cheated by the company due to the poor build quality and exorbitant pricing for repairs and replacement.

I would like Oneplus to provide me with a free replacement for the motherboard and ensure my phone functions as usual.
