Ignore them.  Total scam.  Felony charges are handled by your local DA.  There's no way a debt collector would know one way or the other what charges the DA is gong to file.  DA's don't let debt collectors in on their operations.  Debt collectors have no power of arrest and you can't be arrested for ordinary civil debt.  These scammers always try to magically transform a civil debt like payday loan into some kind of felony.  Total clap-trap.  Don't talk to them.  Don't give them any information and block their calls.

Fraudulent or Zombie Debt Collectors—Things to Know

If you have received a call stating:

1. You have defrauded a financial institution
2. You owe an unpaid payday loan
3. You have a warrant due to an unpaid loan
5. You will receive a court summons
6.  Authorities are coming to arrest you
7.  Anything similar to above,
 a.   Do not give them any information or verify any information for them
 b.   Tell them you know they are a scam operating illegally and that you are   filing a complaint with the  appropriate authorities
Call blocker is your best bet.  
The more information and complaints there are, the better the chance of getting these criminals to stop (or at least reduce the frequency).    
* File a complaint with the FBI on their Internet Crime webpage     http://www.ic3.gov/default.aspx
* File a complaint with the Attorney General for the state you live in

They continue to bother  you, tell them you are going to the police to make a complaint of extortion.

The left a message on my work phone.  The message states to press 1.  I decided to call them back the phone rang for over 20 times.  Finally a message starts out "Fraud Investigations and that it!!  They are a scam and report them because sooner or later they will be caught.  What they do is get your phone number when you have a one time or another got any type of loan over the internet.  Number one you will not ever get a phone call stating that you will get an affidavit.  Number two you will not get a phone call that someone coming to your house to arrest you.  Don't let these scammers scare you.  Don't give them any money at all.  Ask them to send you proof, tell them to talk to your attorney because they will then say "Oh I have to transfer you to talk to someone else.  

I got that call today

I saw they called me earlier today. I decided to call back and this man by the name of Cole Trickle (which sounds totally fake) indicated to me that I need an attorney. He said that he was from the Office of Litigation. I worked in law enforcement for 8 years and I have never heard of it.  I then asked for what and he stated to me I thought that you were informed already. He told me that I got a loan and I never paid it back. I told him that it was a lie because I have been having the same account for over 15 years and it was no way it could possibly happen. So, I'm with the rest of you felons I have check fraud and theft. (LOL)!! Please let me know how to stop these people. I let him know that I will be blocking them and please don't call me again. They have too much information on file for us. They make me want to change my number and bank account information. So sad and a bunch of B.S!
