I think it's good to lodge the complaint. Then they will either honor it in the future, they will get on a shit list for dealers from GM and pull the dealership if it's bad enough. GM will stop sending out those things if they realize it's just pissing off current GM owners and they have no intention of making their dealers honor them. I'd file the complaint with the AG too. It doesn't take a lot of time and the only thing that keeps these places from having every available toy to screw with people is for people to hold them accountable.
