A funny little anecdote:
Last night I went to pick up my daughter from a friend's house. Friend's Dad answered the door, then excused himself to fix his FiOS box. He said all the channels were blocked due to the parental controls. I offered to help, but he declined. Later he came out and said CS told him to unplug the box. I suggested going to the parental control settings in the menu. He gave me a blank look, then went away again.
Later, after we got home, my daughter received a text from her friend. Her Dad wanted to thank me for providing the solution.
Apparently, neither the Dad nor FiOS CS thought about the most sensible solution.
