Another unwanted call from this invalid (spoofed) L.A. area number arrived today, just 2 weeks since the last unwanted call on Nov 21. When the answering machine picked up, there was dead silence. Robocallers (unlawful telemarketers) who continuously troll the phone lines do this all the time while desperately seeking gullible schmucks to victimize. Criminals who hide behind spoofed numbers are why you should LET YOUR ANSWERING MACHINE TAKE THEIR PATHETIC CALLS.
