Hatchback/liftgate Lock Problems of Chevrolet Trailblazer

Rear hatch and glass gate binding and won't open without hitting the top body panel and roof. This started way back when the glass hatch just pops up by itself while driving and we just stop and just close it. We really did not pay much attention to it even if it keeps on happening once in a while, so now the hatch won't open and I brought it to the dealer where it was originally bought,they said something was done to it that's why ,and why it took so long to complain and why it just appeared now , yes the glass pops off once in a while so it did not warrant to waste my time to bring it to the dealer, but now that it binds it needs to be corrected, everything in there is still original as I got it from the dealer even the glass security etching and they still accuses us of probably something was done to it. I assure you that it's the original and nothing was done to it nor any accident to it. When they removed the screws I noticed that the clips holding the upper plastic panel pops off and does not seem to fit and bows out of shape , the right side panel where one scew s it to hold the panel popped, I noticed that the 2 main supports holding the whole latch/ gate is not level and both the inner sides seems to be lower than the outside so the clips won't catch, they called for authorization for the top panel but was denied, I think its the main roof support holding this whole thing that's bent out of shape,its not strong enough to hold the heavy rear gate. Now they want me to pay $700+ to repair it.
