I got a call frm this number today. I looked it up and found this site.. they had the last name right but not the first name. I immediately suspected it was a fake company of some sort. Put on reject list for my phone.
They told me I was being served papers also.
I too have gotten same info. When i refused to give them my last 4 numbers of my Social they hung up. After reading what you wrote i called back and told them that they had been turned over to FBI and now they were being watch. And once again they hung up. Hmmm we all need to stand up against losers.
