These ppl have called me using several different numbers. If I don't recognize a number, I don't answer it. They never leave a message. I just "Google" the number to find out who it is. Then, as I just did this number, I save them to contacts under "SPAM" and set it to go directly to my voice mail. When a call comes in from any of those numbers, I never even hear it ring; I just get a "missed call" indicator. Oops -- my bad! >:}
