These idiots called our business today at 1818 hours, long after we were closed. Caller ID showed "Clemonton NJ" so I knew there was a 99% chance it was yet another scam artist illegally spoofing a number. So before the answering machine could pick up I lifted the receiver slightly to connect the call and put it right back down again. I blocked my number and called it back. There was never any ring, just a long quiet and then a busy signal. Yeah, scam artists alright.
My caller ID said INTERNATIONAL even though the area code is southern New Jersey. It was a recording which tried to get me interested in cutting my electricity rates. Of course, I didn't bite.
Recorded message say "This is a public service announcement about reducing your electricity rates ..." , at which point I hung up and blocked the number, although there is a good chance that the number is spoofed based on other reports in this post.
