Too may robocalls

Switched to Cox July 27. Since the switch, I’m getting 20+ robocalls a day.  I set up nomorobo.com, but calls are still getting through. In partular, one with the calller ID that starts with V8. The rest of the ID changes, and always a different number. Message is left that he “local cops” are one the way to arrest. 

I’ve confirmed my number is protected, but calls still ring 5 times, before voicemail picks up.

THIS DIDNT HAPPEN WITH AT&T!
