I got a call from that number, I didn't pick up since I don't like picking up calls I am not expecting or do not know.  When I called them back later that day, a guy answered saying he is from "Educational Direct."  after that, I hung up...  I didn't want to bother, since they did not leave any message on my answering machine the last hundred times they called.  Wouldn't it be easier to leave a message than to call a hundred times?
