University Of Phoenix Tired of getting the run around about my Pell Grant money in whuch UoP has never sent me for the 2006-07 award year still Phoenix Arizona

I have been trying to get UoP to send me my Pell Grant money for the 2006-07 award year and I have had no luck after 3 months of telephone calls. I don't know who to call after the 25 numbers in which I already have, still can't answer the simple question, where is my pell grant money at? UoP has said they sent it to me but I Never received the Pell grant-Ever! Can someone help me find out how to get my Pell grant money-Please!! UoP has told me that I was only awarded a half of a pell grant but I found out that it isn't true and I still haven't heard back from UoP yet! I haven't received anything from UoP for the 2006-07 Pell grant Yet! Who Do I call or talk to in order to get a straight answer at UoP?
