IIPM — not returning retention fees

Address:

Delhi

hello sir, i had submitted my 30.000Rs in IIPM Delhi on date of 10/may/2011 and from that time they did not return my fees, i also logged RTI report to them to give some information on 19/April/2012 and again i did not get any reply from there.
as they are not recognized from the UGC nor From Any other Govt recognised college thats why i opted my name from that institute as on 15/May/2011.
so please tellme what other steps i had to take
