Apple India — defective iphone x every time

Address: New Delhi, Delhi, 110024

I purchased an iPhone X a month back and there was a manufacturing defect, the screen was popping up, Apple swapped my device and I had to wait for a week, now after 2 days the swapped iPhone is also defective and shows yellow screen in pictures clicked from front camera. This kind of harassment after spending 90, 000 is not acceptable. Apple is supplying defective sets each time and spending this much money, energy and time is not possible for a student like me.
