Who called from 3167688736

I didn't answer.  I think I'm on every scammers list to call today.

BLAH BLAH BLAH.......Just another ILLEGAL ROBO-CALL!!!!!!!!!!
ILLEGAL ROBO-CALL for a Google Listing "SCAM" THIS IS A SCAMMER!!

They called all 10 of my offices within less than two minutes. I called the number back and just got a recording. No identification of who they are.
Do people really buy anything from that type of solicitation?  There should be tighter regulations on caller ID. Every caller should have to be identified
