Jawaharlal Nehru Technological University Hyderabad [Jntuh] — Regarding payment of fee for Pre Convocation degree two times

The thing is I need my Degree urgently in Pre Convocation mode, I paid the fee once in NEFT transfer on SBI page on the websiteand the payment was completed but as there was no update even after 3 hours, I thought that the payment was voided despite the fact that NEFT transfer takes time to get validated in 2 hours and even after 2 hours there was no confirmation or recepit number, so I decided to pay by Debit Card in Billdesk and this time the payment was successful and I got the receipt. I want my refund of the fees that I ended up paying in the NEFT transfer first time ie 3515.
