Got call from 614-329-0516 at work - Call went to voice mail a Mr. Main left a message for Miriam and asked to be called back at 866-547-5413 ext 165. From notes on other site for the 866-547-5413 number, it seems to be a collection agency called Reliant working on behalf of some university for collections.
This is what I found at their website (http://www.reliantrecovery.com/services/)
