Apple India — Unethical replacement repair strategy

Address: Kolkata, West Bengal, 700071

I have a I Phone 6 which is under warranty but Apple has rejected to repair because they say component check has failed and when I asked them where to solve my wifi not getting connected problem then they said that it has dents in the body that can be a reason for hardware failure so you pay 26999 and get your phone replaced.These are purely unethical means to collect money from customer when the phone is in warranty. If Apple can not repair iPhone then what is the point of selling IPhone in India.
