Online stamp duty transaction failed account debited twice

I did a transaction on GRAS website for paying stamp duty and registration amount 558000/-. Since this was done at 22:30 the transaction failed saying that this can be done only in banking hours. Next morning I did the transaction again and everything went well. But later on when I checked my account my account got debited twice. Now how can I get back the extra 558000/-. Can bank reverse the failed transaction or I will have to claim refund from registrar?
