Cash Advanced America Ryan I had someone named Ryan call me with threats... called my employer, Internet

I had someone named Ryan call me today and threaten me with a lawsuit about a payday loan I supposedly took out... I have no information about this whatsoever.  I asked for information regarding this "loan" and he said he could not provide it to me.  He had all of my information... my birthday, address, SS#, employer, etc...

When I told him I did not know what he was talking about... he became very rude... hung up on me and when I called back... got the same thing.  I told him I was not going to pay unless I had hard copies of any documents he had.  He told me it was all "paperless".  I told him I would not pay.  I received a call from my employer about 10 minutes later saying this person was flooding the hospital line with phone calls.. even said he was my former CEO saying they (the operators) needed to call me and tell me to settle my financial debts. 

They called my employer and talked to the switchboard operators 5 times in 15 minutes... tying up hospital lines the entire time despite them telling him it was a hospital and that line was reserved for patients and families. I have never taken out a payday loan with this company but cannot deal with them calling my employer.   Can anyone help me????
