ACS Legal Company for Cash Advance USA ACS Threatened me with arrest for a loan I didn't take! dot given, Internet

I received a call at work this morning from a man who claimed to be from ACS, representing Cash Advance USA.  He claimed I had taken out a cash advance and not repaid it.  I was a little worried at first, because I had taken out two cash advances over the holidays, but had paid both back, and I was afraid I would have to document that with this gentleman.  I explained that any advances I had taken had indeed been repaid, and he said "you have two choices; you can either take care of this today, or you can go to court and pay $7000.00 in legal fees to get it resolved."  He had all of my personal information, my address, SS#, bank account#, who I gave as a reference.  He read all of this off to me, and asked me again if I wanted to take care of it today or risk going to court.  I told him I had nothing unpaid, and wasn't taking care of anything today.  I hung up on him.  He called me back at work again immediately, and said "You disconnected the call?  (he spoke with an Indian or Pakistani accent) "So you dont want to take care of this today?"  I told him there was nothing to take care of.  He again gave me the name of my pesonal reference (my boyfriend) and said, "I'll just call him and see what he has to say".  I told him one last time that I didn't owe anything, and he said "Fine, then we will just have our cops and investigative team visit you at work", and he told me I would be arrested at my home.  This man as very aggressive and threatening - he just kept repeating all of my personal information, which was really unnerving.

I was very upset when I hung up, and immediately started looking through my documents.  Then I realized I had not done business with Cash Advance USA, and decided to look it up online for any possible scams going on.
