You can go to the small claim court to try to get the money back.
However, it will also cost you money($100+?) to file and depend on the judge's ruling.
The best solution I think, is to use up the money as soon as possible.
Usually, lawyers have a free (half hour?) initial consultation, just find one from the phone book and ask. For my opinion, if the lawyer is honest, he/she will tell you NOT to hire one.
