university of phoenix wont release my transcript and state i owe them money Internet, Internet

i went there back in 2002-2005 when i withdrew, i followed the apporitate steps to withdraw. now i am trying to get my offical transcript so i can go to school, they wont release any information to me stating that i owe them funds but when i look at my account it states i owe nothing. when i call the collection agency it took them over a month to find me  to say i owed them anything and now i am waiting to see how much i owe. as i am waiting i cant get enrolled in school because they need my transcript.  i had financial aid when i attended and no one is showing anywhere where i owe anything.
