Central Seat Allocation Board [Csab] — delay in refund

I Omkar Bandhu S/O Than Singh Bandhu participated in CSAB special round counselling. My JEE Main Application NO. is[protected]. I paid Rs. 16500 as participation fee to CSAB. I didn't get a seat of my interest so i didn't choose a seat in both rounds. So as per rules my has to refunded to me in my bank account but till now i didn't get any refund from CSAB. When i tried to contact them then no one responded to my phone call. I request CSAB to please refund my as soon as possible.
The proof of payment has been attached to this message.
