Empire Financial Firm, Empire Debt Services, Victoria Gomez Scared me by saying there'll be an interception of income Norcross Georgia

I received a message: "Victoria Gomez, I'm calling from Empire regarding a claim we have filed against you here in our office attached to the names and socials accordingly.  This has been placed for an interception of income so it's very important if you wish to resolve it voluntarily first.  That you or your legal representation contact my office immediatly so that we can go over your available options.  I can be reached diretly at 470-427-0318 and again this is Victoria Gomez."

I called her back and advised her that I haven't spoken to my brother for almost two years.  She said that a payday loan for $500 was requested electronically around the Holidays of 2012 in Florida.  She said that SunTrust Bank was the account that the loan was deposited to; however when the loan company, Bahama Marketing Group, tried to collect the first payment electronically the bank account was closed.  

She said that they sent 3 certified letters to my brother's Florida address and emailed him, but no response from him.  She said that the Bahama Marketing Group will pursue the person who can afford to pay off the debt.  She said the loan is now $975; however BMG is willing to lower it to $648.75 if I can take care of it now with the routing number and checking account number.  

I asked her what information is there about me because I know that I didn't approve of the loan.  She read off my full social security number and that scared me.  She said that the settlement expired 9/30/15, but can do a 24 hour extension if I pay by then.  I told her that I don't do checks and she gave me the website to pay online.  I asked her to email a copy of the letter that she sent him.

She emailed it; however it looks like something that anyone can type up.  She said that if I don't pay within 24 hours then I will have to stand in front of a Florida Judge to determine my fate.  The message she left and the 3 times that I talked to her to get more information had shaken me up so bad that I couldn't go into work yesterday (10/6/15).

I called family member to verify this and was advised that he doesn't know my social security number.  I'm still uneasy about this issue.  I'm going to be diligent on watching my accounts and credit score.
