Centurion Bank Limited — not received noc and rc original

Hello,

I have taken centurion bank loan for my two wheeler hero honda passion plus in nov 2004 warangal location and the loan is already completed. I have not recieved any information from the bank regarding collection of my original rc nor noc. I am staying in hyderabad and iam not sure where i should check the details as the bank now as it is merged with hdfc. I have approached hdfc but they just say that they have no information about this.

Thanks,
Muralinath k
