Tele-scammers NEVER leave voicemail; puts them at risk of having Feds ( or InterPol ) using classified Internet phone tracing technology ( yes, such DOES exist ) locate and hunt them down. It's a safe bet THIS particular phone number NEVER originated from Marietta, Georgia; it's a "spoofed" Internet VoIP phone number---likely from some overseas country, like Jamaica, Cuba, India--even Hong Kong....or God forbid, Korea....maybe North ( I wouldn't put it past them )--which is why it's wise one NEVER calls the number back. Your phone's answering service IS your ONLY best weapon in fighting these scammers: Every call they make to someone's answering service is THEIR MONEY WASTED.
