Master card of PNB blocked

I was making an online transaction (registering for GRE test) with my PNB debit card which is also a master card. It required providing two passwords. I got confused which one is which and entered wrong ones three times. Due to this my card has been blocked and i cannot make further transactions. Please tell me what should i do to get it activated again?
