AutoNation Chevrolet West Austin

Unfortunately my first experience with my 2016 suburban in a new town was awful. I took my vehicle in for a routine service with tire rotation. First off, the service rep was very put off with me, from the beginning. As I tried to explain that I had a rear signal issue, wasn't sure if it was a bulb or fuse, he proceeded to ask me the same question 3 times, like he wasn't listening to my explanation. Then he quoted me 60-90 min and it took 2 hrs and 45 min, after I had to go in and question why a routine service was taking so long. When he gave me my paperwork, there was no explanation as to what they did, it was just sign here. As I sat in the car going over the paper work, they wrote that all my fluid levels were normal and that nothing was added. My car and onstar had already notified me that wiper fluid was low, not to mention I watched two men added something. I feel like it was complete dishonesty and I'm not even sure if they did anything. My tire pressure was also low on all four tires, again notified by onstar and my vehicle info, my paper work showed nothing written, not even existing psi. So of course as I turn the car on I notice my tire pressure was still low...I'm not sure why I was treated like this, as I've never had any issue from any of dealerships before but this was so bad I would never go back. Completely unacceptable that they would service a vehicle in such a horrible way.
