DRT & Collaterals

Loan is sanctioned from SBI. we ran the company for 2 years and sold it to Current Owners. ROC changed, Payments for loan done by current owners past 2 years. And company went to NPA. collaterals are still not replaced by Bank as past 2 years bank made sure it did not change their papers to new ownership and kept on keeping conditions. Now bank proceeded with SARFASI. Infact many times they threaten our collateral so we approach the current owners and settle their pending payments. Multiple meetings held with US, Current owners and the bank. Current owners provided alternate collateral's but Bank kept on rejecting their properties after legal evaluation and dragged it for 2 years. Current owners lost interest as it was draining their cash and the bank did not cooperate with them and simply walking away. Our bank sent the file to recovery branch. AGM/DGM of the banks had signed tri-party meetings asking to work with current owners and settle the things. Also collected some money towards pending payments from the current owners. Then continued not supporting us or releasing our collateral. We filed in DRT and got the stay. Still we keep submitting documents as bank did not submit those discussions and collections donew ith the current owners. And Bank now acting as if they do not know current owners and they are considering us as the owners in their documents. They file another possession petition in megistrate court and send agents to take posession. We got stay from the court also. Now they send us notice for online auction while the stay is granted and the case is under progress in DRT. What is SBI doing? is this legal? why are they letting go current owners. why they did collect payments of over 5 Cr from them. and not replace collateral and hanging on to us. Pretending as if we are the owners. How we can effectively win over this bank in DRT. My advocate is very proactive and is informing me the status but iam growing curious as to this tricky situation. And if DRT will support our argument.
