Conrad from Sky something wanted to sell me some home improvements. After telling them I'm on the do not call list, he asked what is the one thing I wanted done to my home? Told him I was going to report him and he mumbled and hung up.
Got a live call (after the usual long silence after answering that indicates a predictive dialer) at 8:30am on a Wednesday. My number is on the National DNC list. The agent identified as "Sky Incorporated" and knew my last name. That was as far as we got. He hung up right as I was about to put him on "infinite hold". They seem to be rather skittish creatures. :)
