I tried with 2 numbers.. I dont want to try with my parents numbers coz they have their own idfc bank linked with that number.. and dont want bank to link the credit card to their account IDs.. I dont really think it will happen coz it should link with my pan number.. but still... Idfc should update their systems.. I mean people have said that they are waiting for 8 months and still they are not able to get forward after providing otp on the page.
