I missed 3 calls from this number while I was at work today, and they left no message. Out of curiosity, I called the number back when I got off work. The phone rang once, then an a recorded voice said, "Thanks for calling. please hold while you're transferred to the next available representative." Then, I was immediately disconnected. The recording gave me absolutely no indication of who I was calling. According to other comments on here, it is a company trying to get people to further their education. I have no idea where they got my information, but I am now on the National Do not Call Registry because of them and others like them.
