Uttaranchal University — not refunding my fee

I have changed my name in gazette of india but not in 10& 12th certificate. Uttaranchal university gave me admission in my old name as they don't follow the gazette process for name change. I realised that all my documents i, e income certificate, caste certificate etc are in my new name and it will be very difficult for me to change them in my old name, so i decided to cancel my admission within a day after admission but they are not refunding my fee. Pls help this is so disgusting. Shame on such universities
