Who called from 6177787390

Caller ID BOSTON MA, which I mistook for a friend's cell. Actually a robocall that starts with "Congratulations!" and ends one millisecond later when I hang up the phone. Blocked.

I got the same robo call 3 times in the last 30 minutes

Same here.   Glad I stuck to my policy of never answering the phone if I don't recognize the number.

My wife picked up. Political poll. Hung up. :)
