New windshield glass is warped is this normal?

I just got a new windshield glass replaced (this is the 2nd one because the first replacement had a manufacturer issue). The lady before the installation this time tugged on the glass by the black area very hard to show me the adhesive on the glass is strong. I told her to stop and she does it one more time.... The camera sensor area is warped. I checked other cars around me and I dont see any warped glass. Is this normal? I will need to call again to complain. What should I say?
