Black Dot and lines on display screen 2021 MacBook Air

I purchased a brand new 2021 MacBook Air 13" after 2 months of using it the display started having issues. First a weird black dot in the corner, then weird verticals lines. I did 3 remote support sessions with apple support. We wiped the disk and reinstalled the software 3 times. It would work for a few days then start again each time getting worse and worse until the full screen went black.

The computer would not function at all. I plugged it into a seperate display monitor and it did not work on that so I new it was disk damaged.

This was during lockdown, all apple stores were closed. I tried to fix it myself. I pushed the screen to move the dots and it scratched a little nothing major it was already not functional. Then I sent it in for repair and apple are trying to charge me for a new display at $900 for "customer damage" even though the computer was not working for weeks before there was any cosmetic damage.

Has this happened to anyone else?

I don't know what to do paying for the repair its almost as much as a new computer brand new and the disk is damaged so it will likely happen again.
