My brother got admission into Bharat University in May 2023, initially we paid 10000 for admission. we have been told that if admission get canceled we will get refund amount 8000. For some reason my brother decided to cancel admission. We submitted the refund receipt to the college in July, till now we have not received the refund. I tried contacting college, but didn't received a response. Kindly help me to get refund amount?
