I actually got a human on this one a couple days ago. It was a scammer from 'USB yellow pages' who wanted to 'update' my 'free' listing when he really wanted me to switch internet providers. It's the same scam as all the others. He has called back twice since then, but I just hang up on him.
this phone no. called on 9/29 and 10/1, he identified he is with yellow page, I stoped him right there and i reported this number to the do not call registry. my number is registered on the do not call list. he is going to stop - hopefully.
