I agree with those who said that looks like impact damage on the road and not from a careless installer. If you didn't hit something and the damage was there when you bought the car then shame on the dealer and whoever did the PPI. The good news is that the damage is most likely repairable by as professional wheel repair shop. I have had similar damage repaired on a Porsche "Sport Design" wheel and including refinishing the machined lip and the cost was ~$125. When finished it looked like new.
