Wanted to give my return business back to Jay Wolf...

Wanted to give my return business back to Jay Wolfe after purchasing my Camry almost two years ago. I worked with Saman and could tell instantly things weren't going to go well. I told him exactly what I was looking for, which they didn't have, I knew what my car was worth and I wasn't interested in all the back and forth. Of course the trade offer was low and he wanted to argue with me and tell me that most people don't know how to look up the values of their cars. My husband and I have traded cars before. We know how the game works buddy! He also proceeded to tell me that my car was not worth what I wanted for it and that there was no way I paid that much for it. He also told me that I needed to consider the 4 year, 45,000 mile services that Jay Wolfe provides as well. I told him that I wanted my keys and that they would not be receiving any return business from me. Who tries to argue with the customer??
