If you want to be entertained all day call this number back, press 1 at the prompt, and then put your microphone on mute. They will think you got disconnected and move on to the next caller. They must use a conference line that stays open continuously so you can actually listen while they try to scam other people. When they finally get someone to provide their credit card number that's when you can jump in and let the caller know they are being scammed! I can't tell you how much fun I've had doing this today and it gives me great satisfaction knowing I am preventing someone else from getting their credit card stolen.
This (and several related numbers in the same area code) are scam telemarketers utilizing a boiler-room filled with scumbags from the Indian sub-continent and supposedly selling "home improvements" of some peculiar and unsavory type. Needless to say, these calls ought to be reported via the FCC online form (though one wonders if the government actually does any kind of investigation or just enjoys the notion of our filling out their unnecessarily complicated form). This operation might be one of those that could be a potential gold mine for someone willing to take the time and energy to investigate the scumbags and then sue them for violation of the Don't Call List and general harassment.
