We have been receiving calls from this number for a couple of days. They (barely) say they're calling from onlinegreenpages.net. I have personally answered 10 calls today. They say they're "updating" our profile. We actually got scammed by something like this about a year ago.
So, all day long I have requested their personal information - name, location, hair and eye color - so I can update their profile. And the last guy - Sean from FL, blonde/blue barely understandable English, had the nerve to hang up on me! I am going to have a list of increasingly personal questions for my "friends".
Do NOT say you are authorized to make changes to the phone bill! Unless you want to pay $49.99 a month.
