View your credit report. (You can do it once a year for free through freecreditreport.com) It was on my experian report. I clicked on "Dispute Claim" and filed out the small report. Experian will handle it from there and send you an email when it is finished. They did this to me also. I too live in Arkansas. They never had the bill so they could not provide proof so both claims got deleted from my report. Make sure you dispute all of them because they are all seperate claims. Hope this helps.
We received a call from them about a bill with Baylor Dallas. They claimed that it was sent to collections, even though we were working with the hospital. When I told her that she has called at an inopportune time, and request a website where I could contact them when I had the paperwork in front of me, the R&R rep became very aggressive. I finally had to just end the call with a statement that I would contact Baylor and find out their contact info tomorrow.
