University of Phoenix, apollo group, uop, uopx Scare tactics for more money Phoenix Internet

I was hesitant about this university and now im three classes from being "done" and i just want out already. This school is putting me in debt and i dont feel like i can get out. I was recently given funds for excess funding. Which means that excess funds from my student loan was given to me. The counselor had informed me of this a day prior to it happening. The money has been sitting in my account and now the school wants it back. What started out as a little over $1500 that i owe back to them has since turned into them saying that i owe almost $9000 from a return to lender fee. I have never heard of this. I tried to pay the 1500 today since my class was supposed to start but they withdrew me from the class. Now the process is starting and the school says i have to pay. What do i do???
