You left out he's also checking when a live voice answers the phone. Sure, he may indeed be a manipulator, but for those who do their "business" stealing information by phone and trickery, answering the phone is mandatory. Without any kind, these guys are harmless.
Caller claimed to be from UPS having difficulty delivering a package to my old address. Caller provided call back number of 718-584-9970 which is constantly busy. Caller asked for new address to send package other than po box.
caller claimed to be from UPS, said his name was Steve Wilson, said he had a package for me and someone else name Rachel, he seemed to want to try to get my apartment number. he had called my brother and my mother, too!
Caller left a message at my parents house saying he was steve wilson from ups and that they were trying to deliver a package to Villanuevo and I was a contact for them or something...my dad took the message. I don't know anyone with the name Villanuevo and when I called back was always busy.
Same happened to me caller wanted new address to deliver UPS package to and said it was from a person I know (who has been victim of id theft). Checked with person I know who said no package was sent to me.
A fraud... don't understand what trying to do, but is fraudulent!!!
