THIS IS AN EXTORTION SCAM. Scammers pretend to be law enforcement (police, sheriff, Feds, AG's Office, fake cop agencies with made-up names) and may be using bought/hacked/phished loan application data to extort money or personal info for fictitious crimes.

I got the same message from Michelle Williams, B* name is not Michelle. Barely could understand her. And she was harrassing me for the funds even after she hung up on me and threatened that going to court would ruin my life. that I would lost me job, family and kids. Then I see you guys' post and told her I googled her she hung up. I called her back and she gives me an attitude, I told her to just quit calling my phone now. I hope she's not serious to where I can go to jail. That's crazy. It's also annoying too, I think she was just trying to scam and scare ppl into paying actual debt. UMMMMMM BILL COLLECTORS JAIL THREATS AREN'T GOING TO GET YOU YOUR MONEY FOR DAMN SURE. I WOULDN'T GIVER HER A DIME WITH THAT ACCENT AND FRAUD TACTIC! SCREW THAT B* !!

How do you stop them from calling every 3 minutes??  This is getting annoying!

I got a call fro someone claiming to be Kelly Smith saying I owed a debt of $580 and if I dont pay I would face a law suit for $10,000. She was calling from "attorney's office" and burped down the phone right before she provided a call back number!!! THEY WONT QUIT CALLING!!!! f**k these fraudulent SOB's!!!!

I received 2 phone calls back to back from a "Michelle Williams" who informed me that I was to be arrested at my home tomorrow morning at 11:30am. She said that if I wasn't home that they would be arriving at my place of employment. I then asked her what this was in regards to and she says "oh, well you should have been notified". I answered with "ya think?". She was very rude and I instructed her that what she was doing was illegal and that I haven't been notified of anything at all. I then proceeded to tell her for them to "come and get me then" and hung up in her face.
