I am Abhijeet Bharti having jee application number[protected] and had applied for special spot round and was alloted seat in round 2 but i had withdrawn my seat so fees paid by me was to be refunded but till now it's not refunded and when i try to login to update bank info, sites say that i can't submit refund request and contact csab admin and when i try to call them they never receive call and also i had send gmail regarding this but they don't reply from their side. I request them to refund my money back as soon as possible...
