I keep getting calls from this number but they leave no messages.  I refuse to answer calls.  I don't know why these calls are coming to me but I'm getting sick and tired

CID is from "Strategic Mrktg" - has called several times. I also am getting several unknown calls.

Got the first call on 10/12/08, as usually no message was left, so have no idea who/whom this call is about.  I do not know about the rest of you, but I am getting sick of this calls, not just from this number, but from all the other "Unknown & recording calls.
