Scammers!!!

A car was advertised on Facebook. I sent a request to find out if the car is still available. I requested if we could make arrangements to see the car. I did my research and found that the car was overbooked. I then told him that I am No longer intrested in car, as it is overbooked. The persoon then started telling me that I am a criminal. Started swearing my mother? Is this a way to run a Business? Do not make use of this dealership!!
