Diver Chevrolet

I negotiated a good deal on a 2013 Chevrolet Volt. I am coming from New York City and I called on March 20 to negotiate the price. This dealership is located in Delaware . I was emailed a bill of sale stating that the Price of the car was good until Monday pending I came with documentation and payment. I call today, March 21 before I prepare to make the three hour trip to Delaware. I spoke with the salesman who stated that the car actually sold this morning. That's business, I understand you have to sell so who has the cash or finances at that time. What really bothers me, what I think is unethical, is that no one from the dealership bother to call me to tell me the car was sold. You hear about these things all the time, that someone from out-of-state comes to get a deal and the car is sold and now that person is stuck at the dealership possibly in a position to buy a car that they don't want because the original car was sold. One of the salesman here noted to me that it was just a miscommunication and the two parties I was negotiating with were out Saturday. I find it very difficult to believe that no one from the Friday shift told the rest of the salesman hey there is a person coming in here with $20,000 just a heads up. I chose this dealership because they had great ratings on Google and other dealership review websites. But I had a really bad experience with them and the type of service and courtesy extended to me what's typical of a used car dealership. I'm not sure I would let the people at Diver Chevrolet sell me a bottled water or fill up my windshield wiper fluid. In all fairness, I did not technically complete a purchase or transaction with this dealership, but I think when you look at the context of why that is it speaks volumes as to what their level of customer service is for potential customers
