All India Institute Of Medical Science [AIIMS] — request for refund of extra payment done for aiims ug 2019 final registration.

Sir,
I had done my payment twice for aiims19. I made my first payment of rs. 1500 with reference number :- cpn7774895 on[protected] and amount was deducted from my account. But, payment status was not updated and i couldn't proceed to the further steps to complete my application. It shows an error saying "a payment has already been initiated from this reference. Your request can't be processed." i waited for 24 hours for payment updation, but it was not showing success. So, on[protected], i made my payment again through same sbi debit card and submitted the application successfully. I have made my payment twice for one registration. Since i have not got a refund for the same, hence i kindly request you to refund my amount with reference number :- cpn7774895.
