serial abusive scam/spam/phishing/spoofing POS criminal caller to my do not call registered number. Only info on my ID box says: Los Altos, CA =obvious criminal. You see, he is trying to steal personal ID to use in his other crimes which likely include human trafficking. When I call back, the 'ring' squeaks angrily like it's a fax machine. When he scam calls YOU, after blocking him of course, please contact law enforcement.
