Glad it worked out. And sorry that you had to deal with that complete lack of customer service.They 100% lied. Today it occurred to me that it was the first day they have ever looked at the vehicle. And the reason I know that is because I get notifications from OnStar saying my vehicle is getting diagnostics ran on it. Today is the first day that I received those notifications l and I revived them each time they tested something on the vehicle.
Lo and behold they actually moved my vehicle into the bay today and worked on it! And guess what, it was fixed within a few hours. The General manager called me and apologized for what had happened and said there would be no charge for the service. He said this was on them and that it wouldn’t happen again.
So I guess it paid off going to the GM.
