Apple India — Iphone 6s Plus

I bought the i phone in the month of June and even it is in warranty but they are not taking care. The device is got bent and it has heating problem as well.

They are telling me that you have to pay 29000/- rs we will exchange the device with new one. but my question is why i will pay even it has problem with i phone and bending issue is with the i phone only. it is manufacturing defect.

Even i bought it rs 70000/- in the month of June only.

I went to service center and i given the mob in On condition and they returned me in OFF condition. And the the device is not getting on now.
