Can't you call them back?

It says UPS on my caller ID,  which I think is a ruse to get people to answer......

Caller said they are the "processing agent from the processing center" When they realized I was on the line, they stopped talking. I hung up and called number back. It went to an answering machine! Scammers!

Got a call from this number.  They claimed to be processing agents for UPS.  They asked me to verify my name.  When I declined to do so I was told in a threatening manner that if it was found out that my phone number had been given "under false pretenses," that it would be added to the "court filing."   Really weird.

They say that I had a law sue against me I gave me another phone number that never answered
