This dealership is horrible, racial discrimination...

This dealership is horrible, racial discrimination and dishonest. I talked to the sales man his name is Mark, before I go there he told me the car is 46,000 with free delivery, when I was settled with him, he changed his words and says it will be more! He tells me that he is not going to do 46k anymore???!!! I show him the text massage that he refuse to admit it. OMG... unbelievable!!! Even more, he went crazy, he and another salesman Dave shout at me few times:"do you understand English?" just because I`m an Asian.
(this is the first post I posted on google because this hurt me so much, I post the text message he text me before as an evidence)
