CA Updates ICAI (12 Points)

when i fill my credentials i.e login Id and password and then press for login button.
then i get a screen where:-

required Bank Account EVC was written.
1. I already have an EVC
2. I would like to generate EVC


:-for 1st option, i did not have any EVC.
:-and if i select for 2nd option i.e. I would like to generate EVC then he said Mobile no. is not matched with mobile no. attached with Bank.
and there is not other option to change the mobile no. in portal or login the portal


now how i can login my Income tax portal?
