Indian Bank — refund problem

Address:

Salem, Tamil Nadu, 636102

Respected sir,
On 25.3.18, i made a payment of rs.1513.28 for jipmer entrance exam fees via net banking. Transaction failed at last step but amount debited in my bank account.
I enquired with jipmer they asked to wait for 15 days to get refund but till now not refunded. Again i contacted them, they suggested me to contact your bank to get refund.
I attached the statement from 25.3.18 to indian bank. But there is no response from the bank after i mailed many times.
Thanking you.
