Key GMC of Rochester

Had a $500 deposit, on a used vehicle, upon arrival to complete the purchase, I was told, it was sold to someone else, and my deposit was only good for an hour, "lie", and , "your trade was not worth what we offered", it was sold out from under me, I was likened to a no show dealer, (insulting) my deposit was a committed offer, salesman said, "oh, i wasn't here when the call come in, sales manager said" oh, i wasn't here when the call came in", seriously, this is BS, "no notation in the system, no call, no text, no email, not a shot, nothing", this is unprofessional, and poor business ethics , just horrible customer service " STAY AWAY"
