I have been harassed continually by these robo calls. If I do listen to message and click on #1 and do get a live person I ask them to cease calling me. Many times they hang up on me at this point, sometimes they agree to take my number off their list but I still am getting daily and sometimes multiple times a day harassing calls.
If this is happening to you pls report the number to the FCC.
It's been calling me the past few days too. Must be a new number for Feb 2013. I wonder if they got the number from Fios? I went into my online account and blocked them from my Fios account..but they'll probably just come up with a new number in a few weeks and call again!
