Department of Law and Investigation Failure to pay loan, wish me luck, Internet

Received a call from the Department of Law and Investigation, Mr. Richard Ronski.  He knew my social security number, bank account information, and even IP address of computer.  He said I took out a loan and defaulted on said loan.  At first I thought it was ligit and tried to gather more informaiton.  Then I quickly realized, it was a scam.  He was not able to tell me WHO I took out the loan with, HOW MUCH the loan was for, DATE, etc.  But I could settle for $895.00 or I better get an attorney and I had four (4) hours to comply. 

I told him I needed time to research with my bank, he said to log on right now and look.  I told him he was CRAZY.  He has my IP address and wants me to log on?  I asked for his companies address and for him to send me something in writing.  He said he couldn't do that.  I looked online and found that many have been scammed by this company (or attempted to be scammed).  Once I realized, I called him back and told him that I knew it was a scam and to leave me alone.  He and his "supervisor" Officer Brown called me at work 5 times.  They asked for my manager.  At first I told them no, but then I went ahead and had her call them back.  I also notified our IT department, Telecommunications, and Law Enforcement (I work at a community college and have access to these things). 

They continued to call for 3 days about 20 or 30 times, using 3 different numbers:  (646) 794-5544, (408) 520-2484, & (760) 933-5403.  Also the individuals changed.  Sam Bot, Sandy Campbell, Officer Harris, to name a few.  They also called my home and left messages, stating if I did not return the call all they could do is wish me luck as this horrible thing unfolds upon me.  I would return their calls, when from a different number, from work.  I told them upfront that our Telecommunications department was tracing their call.  They would hang up quickly.  After three (3) days they've stopped.  It's been a week since the calls started, so I guess I'll see if they've given up.

I checked my credit and placed alerts.  They hadn't gotten there yet.  I also checked my bank account and everything was good there....nonetheless these people have to be stopped.

Oh and one more thing, they ALL had heavy middle eastern accents, despite their American names.  And they All read from the same script.  Threatening to send law enforcement to my work to arrest me, etc., etc.  BEWARE!
