             I assume IT portal. The best way to link a bank account is to login thru banks Internet banking facility to IT portal.
The account gets validated instantly as long as your name, PAN, mobile and email match.
I did the same thing and removed all other failed accounts or left them as it is in my login.
If your bank does not have internet banking, open an account with a new bank that supports this and get it linked quikcly.
