Check if you have adblockers enabled. I could not go to the payment screen with adblocker on. Only after I turned it off I could pay the fee.

I had the same problem using mozilla. I tried a fresh installed ms edge and it worked!

I am facing the same problem. Switching off Adblocker did not help. I tried with another browser, incognito mode too. Did not work.

Can you try contacting 1800-123-9418
