Tony Domiano Chrysler Dodge Jeep Ram

I bought a used car was told the payments eod be around 265 per month after signing the papers .The sales man tells me that they made a mistake and that the payments are now 317 a month also found out that the car is worth 2000 dollars less than they sold it to me on Kelly blue book. There was also cigarette butts in my ash tray after I took the car home.they did not even clean up the car.after a couple of days Eddie Gallagher the sales man say I still owe another three hundred dollars to the dealership?? Ya right I think I been screwed enough by them!!!
