Hello Student

To solve this problem you have to wait at least 7 days to observe whether the payment is showing successfully done or not.You have to send an email to the bank authority from where your account is existing. You should place a request letter to the bank authority for your payment details statement from the respective date of the year. They will give you the account details one or two days within and he will understand if you payment for registration have  been done . Even the payment details showa that the payment has not be done then you have to request to the authority of the bank to complete the procedure of payment for  registration. They will do the needful at an early date.

Hope this will help.
