[Resolved]  PNB — loan clearance

With regard,
My father had taken a loan from PNB of 1.5 lacs, and had paid all the installment and got a clearance certificate from the bank after all the compermisation three(3) years ago, but after three year bank is saying that there is still some ammount to be paid, and we have to pay that anyhow.
the matter is that, if still there is some amount to be paid, then how the bank has provided us the clearence certificate.
