Glad I'm not the only one. It called me twice today as well. Nothing but silence when I answered, then as soon as I hung up it called right back to the same results. When I tried to call it back tonight, I got a message that the number was currently unavailable.
3 calls from this number in quick succession on my taxpayer-funded Blackberry. Grrr. Something about a poll about excessive spending in Washington. Probably an election pitch disguised as a poll.
Got a call from this number answered it and the line was silent. During the silence got another call from the same number and when I answered it the line had a copy of what my voicemail replies to someone if I am unavailable.
