Bad repairs

I bought 3 x Samsung 32 inch Samsung G5 monitors which are curved. On all three of them the screen (LCD Panel) is pulling away from the frame. Several bugs climbed into the one and when trying to remove them we broke the LCD. Samsung quoted us more to repair the screen than it costs brand new. The other display just stopped working... we sent it in for repairs and collected it last week. Today is stopped working again. Exact same issue.
