NIIT — Fees Issue :: Commitment of Discount but not given at the end of course

Let me explain some important points as given below: June 2014
1. Total fees for 3-year RGNIIT diploma course
Rs. 139000+12.36% tax = 156180 /-

2. There is the final commitment at the end.
After a scholarship of Rs. 10000 the fees structure as below.
Rs.[protected]discount) = 129000+12.36% tax = 144945(Final)

then first fees paid by cheque of Rs. 14000 after that fix installment of Rs. 5500 for the next 24 months.

Here is the figure already paid by me, 5500*24(Monthly installments) = 132000+14000(cheque) = 146000/-

Please help me to complete my course or refund my fees and also take action against wasting the time of 7 years.
