Caliber Collision - Marietta

After a wreck last year, GEICO instructed us to take our car to Kennesaw Mountain Collision (now Caliber Collision). The repair had a lifetime warranty. Now in the same spot that was repaired, we've seen a small rust spot develop. We took it to the shop this week to have them look at it but they can find NO RECORD of our car being repaired there since they switched companies. The GM was called out to look at the car when they couldn't find the repair invoice and were told that the spot was "obviously" brought on by a rock hitting the EXACT spot where the car was repaired. Uh-huh. Sure. More like you lost our records and don't want to honor the lifetime warranty of our repair because it was performed under a different brand name. Thanks for being shady, now we call GEICO.
