This number calls anywhere from three to six times a day. It's apparently a scam or something close since the rings stop after four or five. When answered, no one talks and after a brief pause they hang up. This has been going on for over a week, every day. Just let it ring. You can file a complaint with the FCC at http://www.fcc.gov. They do respond. I reported one early this month and got a reply via e-mail. Also the calls from that number have stopped. You can also file a complaint with your states Attorney General office. Maybe if enough people do this, these jerks will finally be taken down permanently.
The FCC replies are computer generated. I reported every call for years and kept track. The FCC never did anything, either on mine or on anyone else's as near as I can determine. Probably one reason the FTC was brought in.
Over the last 16-plus years, all the FCC has done is be a rubber stamp for the business friendly congress on TV network, telecom and ISP issues.
