I'm getting the same threatening calls.   I have resorted to blocking the number.

Same thing as all the others.  Each time the recorded msg sez that this is my final notice.  But of course they call again.  What is their scam.  I called them back and cussed them out.  They called back with an attitude.  What is their game???  I told them to bring on their process server.  Kinda hard for them to do when they are out of state!!!!!!  I'm gonna report them to the Nebraska Public Service commission.

did you call back?

calling me at work and home threating to serve legal papers for a debt that is already been paid over 2 years ago.
