Check Reslutions

I am trying to see if anyone has dealt with this company. I recently got a call and they claim that they have a summons that needs to be served on me and that I needed to call some 800 number asap. I called the 800 number and was told that the company was chec reslutions and that they filed a summons in my local county for a payday loan I had with check n go. When I said I had no idea what they were talking about the lady said the loan was taken out back in august of 2007 and that i needed to pay. I than demanded to get the number and local address to the court where this summons was filed she said why? I said because I know someone that works at the state attorney office and that I wanted invetigate. She than put me on hold and came back and said oh the summons wasn't sent to your county yet and that I needed to take care of the balance other wise I would be charged with check fraud. Is this legit or what? All the research and knowledge I have says that this is not legal. Also when I questioned more about check n go she says its not check n go filing charges its First Federal, which I have no clue who that is. I thought check n go used First Bank of Deleware.

Please help.
