okay guys, i bought a jeep middle to end of april. well....i traded my vehicle...2002 dodge ram quad cab 4x4 slt 360 in for it. anyhow....they gave me 18500 when i owed 18700. i just recieved a letter from diamler chrylser stating i owe $902.14 for missing mays payment and tacked junes onto it with late fees. i was going to call diamler chrylser financial and tell them whats goin on, then call hall and tell them how happy i am for them screwing me over on the pay off....not to mention i have been recieving letters in the mail from other credit unions thanking me for inquiring with them for an auto loan. must have checked 5-6 companies when i told them i want diamler chrysler....i didnt say anything when they came back with some local credit union. anyhow...before i blow up at the dealer....what should i do...should i expect any reciprocity, what am i alotted, how should i go about it to recieve the most benifits to me and screw them right back?
