The university is very irresponsible on refunding the the money back. Which was paid to university as 1st term fee. I paid 40k rupees to the university but i didn't get even single rupee back to
I cancelled my seat in December went to university and gave cancellation letter in the month of the December .but i didnt get any response from the university. They had Said that it will take 3 months from date of cancellation means upto february. But no use and if I call them they are saying that you should have to wait for one more month. If I wait for 2-3 months it will complete one year. How much long i should wait for it
So please solve my problem immediately .
