Its was some annoying automated message from US Educator Search, or something along those lines. I called the number back to see if I could be placed on the do not call list, but it was still an automated message to enter me into tonight's sweepstakes. I figured if it didn't let me hit some number about not calling again maybe I could go through their 10 minutes annoying questionnaire I would be able to. But of course at the end of the survey it just said I was entered and I would get a call back and hung up on me. So there is no way to have them not call back.
