Cab messed up

['65 chevy lover]

I'm trying to get my truck finished, finally done but, after putting on passenger side door, the door does not fit. I had body work done by a local shop. Inner/outer rocker panels, cab corners and part of the floor. After trying to install the door, the opening for the door is around 1/2" too small. Then, I noticed the bottom of the rear glass opening has been bent inward approximately 1/2" to 3/4...so much so that, the rear glass would never fit right. I never noticed this before. Its been a year or so since I got the truck back from the place that did the work so, don't want to accuse them of something without knowing for sure. Unfortunately, I don't have pictures because I am using a tablet and can't download them. I just want to get my truck finished! Not sure exactly what I'm going to do about it
