How to unblock my debit card of punjab national bank?

Hi, last night when i went to withdrawl my cash at the nearest pnb bank atm my card get blocked. What happened at that time i didn't able to remember the pin code of my atm properly and i think i have done 2-3 wrong password transactions. Please help me what to do to unblock it my father will shout at me.

It will get unblocked after 24 hours and don't try to use it with wrong password if you do this in your upcoming transaction you will face the same problem again and again.
