Gerber Collision & Glass repaired my 2011 Honda Civic after an accident  illinois

Gerber fixed my car after I had an accident. Approximately 2 years later I was at a car wash washing my car. I noticed paint chipping off the front end of my car which was where Gerber repaired my car. 

I went into Gerber and asked for a manager to look at my car. I showed him where the paint was chipping and he told me I had another accident with my car! No I did not! He insisted I had been hit then by someone while my car was parked.

Gerber refused to fix /repaint what they had originally repaired. The paint has been peeling off more and more on the front end.
