Holy cow. These suckers maneuver the telephonic laws like they wrote them. Blocking their numbers, several different business names, and major cold calling under the guise of "appointment setting for our leader." Lord love you if you fall for these shenanigans and book an appointment or talk to them at any length.
I tried being nice to the man on the phone but it took me 12 minutes 53 seconds to get him off the phone and that's after I called out all his call center technique. (I've run many call centers and trained many agents.)
Just hang up on these fools and since you cannot block an already blocked number, call the States Attorney and file a complaint.
