Triple A Collections I was told i got approved fir financial assistance and that the creditor paid it off. Sioux Falls SD

I get calls saying I owe the debt still.  It went to a lawyer picked up subpena for it called lawyer left message never called me back.  Called Triple A they never return my calls. Then the judgement disappereed.  Now it was dated in May this year. 

Tried to call them get no reutrn calls and just voice mails.  I have asked for answers told them I would pay it if I had to but why was I told it was paid off then a few months later they are trying to recollect it.  I want it removed from my record and this account close.
