6/3/2014 4:24 p.m. Got a call on my home (unlisted NO CALL #) and my machine picked up....some guy let out a loud grunt and hung up. Caller ID shows this is from AT&T Svc Ctr but this is not true. I've received fake #'s from this same fake "caller". I won't pick up on any unknown calls. It's always a scam. Always. One time the trace said the call came from Ballwin, Mo. and then the next trace (same number) said it was from Osage Beach, Mo. It's scam calls.
