I finally gave up and answered as they kept calling. A student representative was calling to find out what I was interested in going back to school for. They probably have a link attached to a job hunting service that I didn't catch and uncheck the box.
I entered my info online for a free mobile phone game app and learned that there's no such thing as free. Started getting calls immediately from this number and each call was about something different - returning to school, cheaper insurance rates, etc. I'm stupid for giving my info to some random site because I have to deal with these a$$holes who won't quit calling. The moral to this story - just ignore any calls from this number.
