Bank Of Baroda — unblocking of my atm

My bank of baroda atm has been blocked due to entering invalid pin 3 times. As to be very clear it was not informed to me by the bank due to msg or email-id about the new atm card. I had to pay my mca exam fees online and i came to know about it a day before when my online transactions was failed. And hence i did not knew the steps to activate the new card. Nor the machine seem to be that user friendly. I humbly request you to unblock my atm. So that i'm able to continue with the payment of my exam.
