unknown caller

Received one call on 10/25/2011 at  7:41 PM.... My Caller ID displayed the call coming from Saint Peters, Missouri and also displayed "IMPORTANT" (yeah right). I didn't answer the call and they didn't leave a VM. Later, I blocked my number and called theirs... It said, "Thank you for calling ***** (I couldn't understand for the life of me what the recording said- started with a "B", I believe). It then gave me the opportunity to press #1 to leave a message, if I want to be removed from their calling list. I didn't do that either, YET any way.... Want to see if I can find any more out about them first..

Got a call, it was a recorded message advertising for some DJ or something.  Basically just a very loud message yelling at me.

called, no message. said "important" under missed call.

just got a call and the id said "important" with the number 6363339039 under it..when I said hello, there was no response so I hung up.
