I dealt with the same deal from the same people about a year ago, now I am doing it with Chase. They're all liars and will say anything to get you to send them a buck. I had a supervisor for collections get rude with me the other day and told me "That if i just send them$65 it would help me out alot" So I told him to F**k off and quit wasting my time, then I filed a complaint with the BBB, which I recommend you do. Also dispute it through all your CRA's(credit reporting agencies). I disputed mine for about 6 months then the agencies that still had the case on file would'nt investigate anymore....So I filed with the BBB on them too.
In my experience trying to deal with collections is a waste of time. The people get commision on what we pay regardless if we truly owe it or not. I would politely tell them to kiss my azz as you file with the BBB. The BBB is most helpful and is the last agency the companies want on their asses...Plus you can check out the NACA site and locate an attorney in your area that specializes in this.
Hint:you can sue them for up to $5000 in small claims court and will win by default because it will cost them more than that to send defense...That is what happened in my case with Chase. After 2 years of the BS(10+ times a day) phone calls I filed on their ass...Best of luck
