Oh. My.... Are you effin serious?!

So... I had been anxiously waiting for my school disbursement money to come in so J and I can handle so of our bills.... so finally I received the letter that my money was ready! yay! So I got it not too long ago and I had verified with my financial adviser that everything that I needed to do was done, she confirmed that everything was okay...so I bought my laptop for school, paid off my loans, and treated the family to some things since money has been kinda tight lately. No, problem right?... Ha, I get an email 2 weeks (yes, WEEKS) later stating that the money was supposed to pay for my classes and that by mistake they sent me too much and my next 3 courses are now UNpaid. So now I am expected to pay $1500 for my next 3 classes. Umm, no. I received TWO letters confirming that they were sending me the EXCESS money from what was 'left over' from my Financial Aid and Grant money. That's their bad that they didn't cover their asses, not mine because now two weeks later, the money is GONE. My family is encouraging me to fight it, my brother is talking to his lawyer to see if we have a case. I sure hope so. I really want to continue you school, and I want to, it just really peeves me that they have left such a bitter taste in my mouth.
