What are my choices against suing my college?

I am a military wife of a US marine and a college student. I would like to
file a suit against my current school, long story short, because of them
agreeing to accept credits from outside institutions (in writing), and then,
after completion of the courses, refusing to accept them because they never
bothered to process the forms even 2 years after they were submitted.

These forms were even signed by the department heads (many of which I have a
copy of), but never filed into their computer system I guess, so they now
are refusing to count them. This has happened for at least 23 credit hours,
but I believe it\'s actually 41 credit hours at this point that I have had
to pay for because they accepted and then denied them after the fact. These
41 credit hours I will have to pay double for basically because I had to pay
the original institutions I took the courses at, as well as the school I
will have to make up the credits to. In trying to remedy this, I have had to
drive to the school on over 25 occasions (160 miles roundtrip), including
two one-on-one meetings with the Dean, in which he promised resolution. To
this day, no resolution has been made, and the promises the Dean himself
made to me have not been kept. Each time I have fulfilled the requirements
they\'ve offered me, they then tell me I am going to need more courses
because they then find even more to reject. This has even happened with
classes that they processed the transient credit forms for. I can be a lot
more specific on the phone or in person. I\'m just curious as to what I can
do to get this resolved because it is costing me a ridiculous amount of
money over what I should have paid (I should have graduated in May), as well
as causing me to have missed my husband\'s return from Iraq because they
never bothered to complete my paperwork within almost 3 years. Almost all of
the problems I have had with this institution, I have some sort of paper or
email documentation of. Of course, for the forms they never processed, I
don\'t actually have a copy of them since they only send them after
processing to me. Please help me figure out what I can do. Thanks.
