The Patterson Group, Inc scam rip off Columbia South Carolina

These people called me 5 times within a time span of < 10 minutes yesterday 03/16/15. They refuse to give any details. I asked for the name of the company, the name of the caller, the company's license number, their address. They refuse to give any information. They say they wish to avoid 'possible civil action'. One caller said he has"legal papers' on his desk and unless I 'clear this up" he will "serve the papers in 5 to 7 days".  Yet, they won't tell me  anything except they want my DOB and SS# and address. When I tell them I have recorded all the calls, including this one - they hang up. Now today, March 17, 2015 they are calling me again. Several times. Finally, I am advised unless I clear up the debt of $1,689.00 dollars over the phone I will face 'a lawsuit' and will probably be arrested. Listed are all the numbers on my caller ID cell phone they call from - 205-623-6886 ; 256-898-3627; 256-281-4021; 256-898-3627; . This is absolutely surreal and I don't know how to fight someone, something who refuses to give me ANY information at all. I had to research their number to get the name of the company. Then when I called them to make sure I had correct place.. they talked for a moment, then hung up.--- Then finally a woman claiming to be 'BETHANY MORRIS" advised my wife I owe a debt from 2005, or possibly 2008 Ms. Morris was not sure... She was willing to take payment over the phone for as little as a dollar as long as we went immediately to a store and purchased a 'green dot card' and called her back with the information. She claimed they are in Columbia SC but did not know the address, wife was willing to hold. After holding for 26 minutes and 18 secs... voice came on and said if wanted a returned call would have to leave a message.
