Xiaomi India — warranty claim-display issue

Address:

Vadodara, Gujarat, 390019

I am writing this mail because i am completely helpless due to response from mi services team.
I bought a mi tv 4 a pro 43 inch (Serial no.- 19310/[protected] a month ago. Suddenly i found a crack in display. I called for warranty replacement but mi team denied for the same. As such there is no trail of physical damage. The service engineer told me that even if you will place a finger on screen this will damage a display. My question: is this the quality of mi products?
Also engineer agreed on the point that there is no trail or spot or sign of impact on screen. Still the said this will not cover under warranty.
