I was applied for pan application on 20th may 2019 on nsdl. I completed 90% of application form and they asking to pay 150 rs and i paid that. But the application is not completed due e-kyc failure. Later they displayed message like you will get refund your paid amount in 7 days. but still i did't get my refund amount. so please help me to refund the amount from nsdl.
