My truck was in for service earlier this week. I paid the bill in full a few days ago and went to pick it up today. Because it was after the service departments hours, they did not want to release the vehicle. Even when presented with the receipt they still did not want to give it to me. The GM even tried to pulled the "I served in the navy for 20 years as a Chief" He was quickly shut down when I told him I have served almost 21 years and I'm still on active duty. Plus I was enlisted for the first 9 years of my career. What horrible customer service.
