I owed back state taxes (KS) and they were turned over to collection with NCO Financial. I called NCO and they offered me, in writing, a settelment for about 80%. I sent them the money within the time limit they required. It has been three monthes and they still have not informed the state that the debt is settled. I have contacted NCO several times and they say there sorry and they will take care of it right away, and yet they have not. Is there any legal action I can file to force them to do there job? I have leins from the state taxes I'm trying to get lifted and can't till they do there job.
