Car would not crank. Car cranked 3.5 hours later. The Service Director, approached me and asked in a rather hostile manner, What am I going to do, I answered, I am on the phone with GM Relations. I asked if he had an attitude after stating that I should appreciate what they are doing, I replied, that l am having a hard time renting a car for a fail on your part to diagnose my car, especially considering the large cost to me for the holiday weekend. He said You should be grateful that we are even doing this out of goodwill, because we dont have to. I expressed my DISGUSTING treatment. I have never been so disrespected not only as a customer, but even more as a women. I am certain that I was completely and utterly under minded not only as a consumer, but a person. Its unfortunate that I had to endure such arduous treatment, and I thought that GM had more reverence for its clients. Its important to not lose sight, that it everyday people like me that keeps this business thriving.
