A scam - they fax a form that looks like a legit Yellow Pages order form and when you sign to "no longer receive advertisement" You are actually singing for a service that does not exist and they try and bill you for 1200+ a year.
I got a call from the same number at 4:30 am I tried to answer it but was too late and they didnt leave a message. I have added the number to my call screen feature... hopefully I wont be hearing from them again...
