Caller type: Scammer/Fraudster
An unwanted call from this Los Angeles area cell number arrived today. When the answering machine picked up, the caller responded with dead silence. This is the tactic of robocallers (unlawful telemarketers) who continuously troll the phone lines, desperately seeking gullible schmucks to victimize.
Telecriminals like this one are the reason you should LET YOUR ANSWERING MACHINE TAKE THEIR CALLS!
