Gerber Collision & Glass

from my only experience there, i have reason to believe that they are not operating above bar. the interested may read on:
i had elected collision revision to repair a 2000 audi a4 after it had been hit squarely on the passenger side front wheel by a slow driver driving perpendicular to me (this is to give you an idea of the damage).
the car had passed all manner of inspection by audi a month before the accident at a yearly maintenance appointment, particularly suspension and fundamental support. collision revision’s estimate was a week for repair. total time in possession of the car was one month. they had never initiated a call in the first three weeks to tell me how progress was making. i had periodically made status calls and was given the onion/​layers of complexity analogy/​line. no mention was made of unavailability of parts.
about three weeks in, they call me informing me that the frame is bent, but not in a way that would have been result of the accident. they released the car back to me with a waiver of liability saying the car was unsafe to drive.
that audi found the frame up to standard prior to the accident, there was no service-​side communication to me for three weeks, and the presence of a waiver at pick-​up time lead me to believe that collision revision was responsible for additional car damage and did not want to file a claim with their own insurance company to fix it.
