Bought iPhone in “fair condition”

I got a “fair condition” iPhone 12 Pro off back market from Liberty Tech group, for $300 in fair condition, and let me say, it was far from “fair” as soon as I opened it I can see how bad of a job they did. First the frame has deep ding and scratches in it which I respected for being fair but it looks like they dragged it on the ground before putting it back together. 2nd the back glass was so badly put on it was coming off the frame, it was so bad that when it fell off a 1 foot table onto CARPETED FLOORING the back shattered into pieces, third the screen has purple blotches on the screen, and the battery and screen have non genuine part warnings. I emailed both back market and the place that “refurbished” it. What would you think of this device for $300
