Terrible service from David, useless panelbeater

This is the worst service I have ever experienced from an automotive repairer. A year after having our vehicle painted, it starts chipping off, I took it in for an evaluation and they insisted I am an idiot and cannot understand why their paint job is chipping off. Nowhere else on the vehicle is the paint chipping but where THEY painted. David promised to call me back with further details and one week later still no call? Terrible service and no idea of how to keep customers.
