IIBS — Regarding my refund registration amount

Respected sir,
I had made a payment of ₹50000 on 7th March To International institute of business studies (IIBS) for my admission in pgdm program. On 30th March I have marked them the mail to cancel my admission because my financial issue, I want to take one year drop.
I don't want to take pressure of education loan in this difficult situation.
I send 4 times mail to IIBS admission department but yet not responding.my money is not yet refunded.
It's been more than month and everytime I call them they say that money cannot be refunded by the government body.
Please look into the matter and I need my money as soon as possible
I need to help my father in this difficult situation..
