got a call from this number saying I had a fraudulant pre medical claim with a case number and that I needed an attorney - wouldn't I know if I had a lawsuit pending?

received call wanting to give message to next door ,??

Keep getting calls from this number, say they are a 'special' investigator, investigating some kind
of criminal activity, last call was from a Paula Cooper. Background noise sounds like a phone mill
lots of other people making similar calls. Some what threating phone message.  Says she's a
BLAS investigator, what ever that is.  Poor connection, like cell phone or such.

Getting calls from this number claiming that I am the subject of an "investigation" and that action is going to be taken against me.  

Got a call on my business line this morning.  It was all automated, no chance to tell her I have no pending charges against me.  She said I must call back as she was giving me one last chance to make this matter right before legal proceedings were brought against me.

I have no idea what she is talking about.
