David, when you signed the contract, did you get a full disclosure of what your financial aid covered? Sometimes it would not cover the whole thing but with this being an online university you would think that they would not have as many expenses as say a traditional four year institution.

As others have said I'd look into what your state Attorney General has to say....also take a peek at the Better Business Bureau for Phoenix University....if they have a lot of complaints lodged against them, then I would say quit while you're ahead and find a local college/university where you could take classes online and in person.
