hey this might sound a little naive…
but still this is what I feel,
do u know any lawyer in Bangalore who could help u with some legal notice or something..I agree with others that getting a legal settlement can take several years and cost them a lot of money, but may be a notice of legal action might frighten the college authorities. Also, is it possible, to publicize this through the media so that somebody who is influential and kind hearted enough will come forward to help.
