Hi

This kind of problems may occur due to different reasons such as Server Lag, Banking problems etc. Now if you have paid the money then I would recommend you to wait for 1-3 official days. If the payment is confirmed then its ok, if not then you should check your bank account, the money you have paid would have returned to your account. So you have to pay it again. Now if you don't get the money and if you don't get the payment status updated (this kind don't occur  but if we assume) then I would recommend you to contact the NTA helpline number.

The contact details are:

• neet@nta.ac.in (mailto:neet@nta.ac.in)
• 0120-6895200 (tel:0120-6895200)
• 011-40759000 (tel:011-40759000)

I hope this answer helps. All the very best for your future endeavors!
