University Alliance Charging student for tuition financial aid should have paid for Tampa, Florida

I was coached into signing up for school by this company, I informed them that my financial aid was not completely process and that I had no job.  I also told them  until it is throughly processed I would  rather not start or sign up for my class because I do not have the money to pay.  They insisted that I did sign up and that once my financial aid went through that the school Florida Tech could go back and get money owed to them.  I had no reason not to believe them since this is for education. 

Then after the deadline for me dropping the class they contacted me and  started telling me that they haven't recieve my high school transcript and that they keep calling the school for it.  So I told them I would fax the copy I had of my transcript to them and I did , once they got that they said the transcript  it  needed to had  come directly from my school to them them ,so I  contacted the school and had them mail them a copy.  Once copy arrived they stated it was too late and that financial aid would not pay for my class for that term and they billed me 3,188.48. 

Now I have no job but had to agree to pay them 89.00 month for 3 yrs just so this would not go on my credit record.  I told them this is not fair they told me because I did not sign up this term financial aid won't pay I told them I refuse to sign up again because I may end up owing more money they then to me to contact there billing dept to make payment arrangements.  My problem is I gave them everything they asked for but they waited to tell me about the transcript after the deadline for me to get the financial aid award for the school.
