Apple India — iphone 8 plus

Address: 380015

Iphone 8 plus stopped working on it's own. Black out screen and never started. Since it was in warranty period, i contacted the service station in ahmedabad and finally the device was sent to bangalore. The bangalore office after several follow ups shared that the device was damaged internally by an external agency whereas the phone was never given to any external agency. They asked me for stock replacement at a cost of inr 66, 000.
