Andhra University — Applied course was discontinued

Address: Vishakhapatnam

Hi I've applied for Pg diploma in disaster management at Andhra University and paid ₹8000 for the same. After 3 months the university told us the course is discontinued due to poor enrollment. They asked me to send details for refund. I have submitted the details on the same email id and even called them several times. It's been more than a year now and I haven't received my refund.
