I work for a bank,  I am an admin.  They called to verify the information for my boss' American Banker " free subscription" and were asking me to verify his address and then tell his name.   But we pay for our American Banker, we don't get it delivered physically.   So I kept questioning her about why she would need me to give her his information if it is already in the system and they send it digitally.  She couldn't explain to me how she didn't have my bosses name and kept saying she was trying to "verify".  I said if you Verify then you have his information please tell me the name you have on file.   She didn't have it....So i finally said look we have a paid subscription so thanks but no thanks.   She finally said   " ok well we thank you for your time".  Think it was total BS personally.

I got threatening phone calls from this number that Plain Green Financial had sent them a notice to call in a loan.  They explained that they were issuing a warrant for my arrest and I would be jailed for 120 days.  I asked for them to email me the documents that they had and were supposedly reading from and they refused unless I paid them $50.00 on a credit card.  I then called Plain Green Financial and they said that they had never heard of Legal Research Group.
Please be very cautious.  I have consulted with an attorney into this matter.

I also got a call from some people in the Grand Prairie, TX area calling themselves the Legal Research Group. Phone number was 469-789-7020.  They claimed I owed money to a creditor and they were going to serve a warrant fro my arrest and charge me with a felony.  They sent me an email with an attachment that was a Demand Letter. Their letterhead had a PO Box on it and no physical address and was not professionally done.  The phone number was a land  line in Grand Prairie, TX, but the letterhead had a Dallas PO box on it. I have not heard back from them today and they said they would give me only today to pay it. They first called my brother and gave him these details without my permission.

Don't tell me, Indian accents and you have to pay with a Green Dot card or something similar.  Assuming there is no basis for the "owing the money" part, this is a total con.    Take it to your local police and file a report;  this is extortion pure and simple.    These characters probably aren't even in the US, but an official complaint will cover you in the case of them later playing fast and loose with your bank accounts, credit rating, calling you at work, etc.    Also, file a complaint with the Consumer Financial Protection Bureau.   Threatening jail over a private debt is clearly illegal.  http://www.consumerfinance.gov/complaint/  

Also, since they used Email to perpetrate this fraud, report to the FBI's cyber crime unit at IC3.gov.

I suspect CFPB and IC3 are already aware of these clowns; they have to hit a lot of victims to make any money.  Don't let them bully you.
