I've been receiving calls from this number on my cell which comes up as Sheridan, IL every single day this week as well as quite a few days throughout the month of March. I finally answered the call today and heard a beep, but no one said anything on the line. I called it back & a recorded message said "THANK YOU FOR CALLING THE SWEEPSTAKES CENTER & RETURNING OUR CALL". I of course then hung up & blocked the number from my phone. They seem to be annoyingly persistent!!!
