An unwanted call from this Seal Beach landline number arrived today. When the answering machine picked up, there was dead silence. This is the hallmark of robocallers (unlawful telemarketers) who continuously troll the phone lines, desperately seeking gullible schmucks to victimize, even on Thanksgiving weekend! According to www.whitepages.com the number is listed as Henry Engineering and is described as "scam or fraud." Case closed!
