I tried to fill the pan application through the nsdl website and selected the e-sign verification process. after filling in all the required details it took me to the payment page and I have made my payment of Rs. 106.90 using Paytm.
The payment got deducted and it took me to 'your request cannot be processed, please try after some time. I am not able to proceed further.
