Got a call from this number on my business line but no message was left.  I called it back from another number and the message advised that I had won a trip to the Bahamas......  Yeah, right.  Hung up at that point.  Judging by the lack of entries on this number they are just getting started.  This number comes back to Alltel according to this web page;  http://www.merchantcircle.com/business/Alltel.800-255-7351
