I had been a loyal customer of this dealership for a couple of years until this past weekend that I took my Husband's Nissan Titan to check on the AC. Everyone in the service dept is very nice and attentive. But I was so disappointed and will never go back there, I decided to leave the truck and get a rental car since I knew that it wasn't going to be ready and my son had soccer game at 1 o clock and if I waited he would've missed it. Well everything seemed to be fine until they gave me the rental car and when I was leaving the parking lot and the car had air pressure light on. I turned around and went back to have them check on it, there was a few employees and one of them came to me be very nice and I said that the air pressure was low, he said no worries I will take care for you. I had my 10 year old son and my 2 year old daughter with me , I took them out of the car but never thought about my purse or my phone and left them in there. while he was fixing the car I regretted about leaving my the purse and the phone in there but I though was just a random feeling. when he brought the car to me he was like in a rush and went inside right away. something inside of me was tilling me to check on my purse it was just a weird feeling and I pulled out my wallet and was missing $60. I went inside and asked one of the guys that was outside for the manager. When the manager came back with the guy who took the car said that he was just the wrong person to blame in, that he new him for a lot of years and that he will never do that. He said that the guy always has cash on him and that he doesn't even doubt about him. He said that it was maybe a mistake from my side and that I had maybe expended the money or misplace it and that I didn't even remember. I think the manager was rude and disrespectful to me he didn't even doubt on his employee just because he knew him for several years, but he didn't even questioned him on front of me. Instead the manager made me feel bad saying that the guy could lost his job and trying to make feel guilty about. He said that he was going to give me the $60 back whenever I had to go back for the truck, but that he thought is that it was a mistake from my side and just didn't even remember. I told him that I don't want the money back since i felt insulted and he was very disrespectful to me.
