Tata Motors — Tata Nexon infotainment system

Model - Nexon XZ + Diesel
Problem - infotainment system back panel and base crack opening.
I had give for third service at Hubli tata service centre and raised the issue.
Harman is almost denying my claim and even tata motors official is denying my claim and they are stating the product come like this only by default.
But I have seen new cars and all is good with infotainment system.
So I want to get warranty claim for infotainment system which is being denied by Harman and Tata motors officials.
