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.
