Dept of Law and Investigation, Don't call them or give them any information. Nationwide

I keep getting calls from different numbers stating that they are from Dept of Law and Investigation.  I have told them that I have contacted my lawyer.  They are saying that my SS# is under review.  Everyone that calls have indian accents, so I do not believe that they are where they say they are.  If you ask for the company, they don't know, do not know physical address.  So I told them to stop calling me. 

If they are a legitimate company they would already have my address to send me correspondence.  I have researched all of the numbers and get the same information that they are a scam company.  So I refuse to contact them.  If it is for real the U.S. Dept of Law and Investigation can contact me.  Don't call them or give them any information.  They try to scare you by saying they will have you arrested, I'm still waiting for the police to show up at my address.
