Complaint Review: autobarn mazda evanston illinois

i decided to buy a new car from autobarn mazda in evanston.
their website says that offer competitive rates direct from the manufacturer and local banks ( http://www.mazdaofchicagoland.com/finance.aspx )
also it says that you can get 0 % financing through chase bank which is a partner of mazda. ( http://www.mazdaofchicagoland.com/manufacturer-specials.aspx?type=finance&sf=1&year=2011&make=Mazda&model=Mazda2 )
but when you apply for a loan they refuse to finance you through chase and give you high apr and lie that your credis is bad even if it is good. so you end up paying at least $3000 more for a car.  
i called chase and they said that they never got an application from the dealer for a loan. then why would they advertise it if this is not an option?
