Call my cell phone everyday and never leave a message. I finally called back and a man identified himself as "Dan" and asked if I was still interested in schooling. I have never called that number and he was very quick to get off the phone and hung up on me. I had to call again and started to get the same question about school so I cut him off (mind you this was another man named "Dan") and told him to remove my number from their system.
I called it back and a woman with a strong accent said I was called because I asked for referal services. It has to do with further education. I asked to be placed on the do not call list. It was the second call in a week. Hopefully the last.
