Duped by a bank official

Sir/Madam, I am a NRI holding NRO account in a nationalised bank. During a visit to India in September 2013, I was approached by a bank manager about the sale of a secured property that was classified as NPA that belonged to a NPA account holder of the same bank. I was assured verbally bank manager that if I pay the loans that belonged to the NPA account holder, the BoB will arrange to hand over the property held as a security in the bank by the NPA account’s company. NPA account holder of the bank borrowed the loan by mortgaging the titles of 1. their home papers held in their name and 2. a land only property held in their company name. In this regard, an agreement was prepared by the bank manager using his /bank’s advocate. It was signed both by the NPA account holder and I with the clause ‘as is where is” saying, after the payment of the loan by me in full, the NPA account holder gets their home and the company will be transferred to me that has the secured landed property in the bank and is held in the NPA company holder’s company’s name. The agreement also said that payment was to be made by me to four different accounts held by the NPA account holder in the same bank. We completed the payment by July 2014 starting from Feb-2014. Initial payment of advance for this agreement was paid to an account in the same bank which we found that it belonged to the bank manager’s relative. I agreed to this arrangement only on the total faith on Bank, with the belief that the landed property is genuine property with legitimate title, as it was represented by the bank manager. We were made to believe the NPA account holder’s company were the rightful owners of the landed property. “Only on this basis that the company is the rightful owner , the bank provided loan to the NPA account holder”, the manager assured. As this property was held with the bank as the security and arranged by bank officials themselves, the payments were made as the internal payments to the NPA holder’s accounts. Since the day of payment in FEB 2014 till now (Feb-2017) , we could not take the legal possession of the property that was held as the security by bank towards the liabilities NPA account holder. The supposedly secured property that was held as the security by the bank did not belong to NPA account holder’s company. The Patta was found to be fake as confirmed by the local Tahsildhar’s records. We are in loss of amount paid and further interest amount since FEB 2014. In our opinion, it is clear that , we were duped by the Bank officials , probably in collusion with NPA account holder. We are made to strongly believe this because the house was passed on to the NPA account holder and the landed property with fake documents was passed on to us. As the NRI account holder I was dealt wrongly with the intention of passing the bank’s liability on me. Proper duty of care by bank officials was not provided to me. Since the payment of amount to BoB towards this transaction, I am under extreme mental stress and financial burden. When we followed up with the banks, they say “the NPA accounts are closed now” and no other comment. Is there any possibility of recovering the amount we paid towards this transaction from Bank? Or alternatively get the bank to retrieve the share of the house property of the NPA account holder that was held as another security at bank towards these loans. Or claim damages from Bank?
