I had created a savings account on ING Vysya Bank two years back. I didnt use the Debit card for a year but the normal transactions used to happen via bank transfers, so one when I went to an atm, the atm refused to take my card - it said invalid card.
I called up the helpline, they informed me that the bank has changed to Kotak Mahindra Bank and I have to go to there main branch with my documents for verification purposes. So after a long hastle I got the card working after a month! I would suggest you to go for a different bank.
