Have received perhaps a dozen calls from this # in the past few days. I always let my voice mail answer but the caller (robo?) leaves no message. I have telemarketer call blocking from AT&T but somehow certain ones get through. Calling them back only encourages them, so would advise folks to simply ignore them.
This number (386) 518-3004 was answered by someone representing a company called Diabetes America. Their number must be spoofed, they are not shown to have a location in the 386 area code.
