National Institute Of Open Schooling — payment has not been updated

Sir, i had made payment for 2nd semester deled exam fees on 19/10/18 and i got a msg for success transaction but still, the status is showing payment not made. This is a completely shameful that nios can't handle a well-maintained payment gateway. It has already been more than 48 hrs and status has not been updated yet. Do i have to make the payment again? And in this case, will i get the refund for the first payment
