Back of screen popped off

I've had this just over 4 months and the cover is coming off of the screen. It looks like it should just pop back on but it won't. I took it to a local computer repair place and they say it will cost more to fix it than it's worth. Super bummed at the quality. I thought it would at least have a 1 year warranty but looks like it only came with a 30 day warranty.
