Dear Arun, please check if the payment hss been debited from your Account. If it has been taken and you aren't being still routed to the next page, there might be server issues. Clear the cache, browsing history, restart and login again to continue with the rest of the process. However if the payment hasn't been debited, you will have to make the payment again and continue with the process. There have been issues reported and candidates facing the same issues got it solved with these steps only.
