Trapped by banking fraudster nexus-with bank official's involvement

Hello Sirs, I am from Kerala, I stood as guarantor(unknowingly) for a loan taken by a fraudster nexus. This happened in 2009 at the time of my daughter's marriage. I was in dare need of money and told this to one of my well wishers and neighbors. My house is situated in a land on which a 220KV transmission line is passing through, and the banks in hometown refused to accept it as mortgage and grant me loan. He told me that, he can manage to get hold with a business man(more than 100Km away from my house) and arrange a loan of 10L from IOB, Willingdon Island branch where that business man has all his transactions. Next day my well wisher neighbor, business man and another person came to my home and advised to go with them to the bank. Prior deed of my property was pledged as a mortgage long back(before the 220KV line came in to existence) for a business loan as a collateral security. They told, it's not a big deal, the manager of IOB Willingdon is his close ally and he wont need much proof to sanction a loan. They asked me sign a notarized affidavit which described clearly that I am mortgaging my property to obtain a loan. We gone together to the Bank, but the Manager was on leave, they called him over phone and he arrived immediately at the bank. He told me that there will be a delay of 2-3 weeks to complete the processing and disburse of money. On my way back to home, that business man handed over 4Lrupees and told me that the remainder amount will be given after loan get approved. After this incident they didn't contact me at all, I got busy with my daughter's marriage and various functions there after. I tried to contact them many times to know the status of my loan, but from time to time they replied that the loan is not yet approved.After an year, I got registered letter from Bank saying that the loan taken by M/s SAS Tradelinks is defaulted and my property on which I am residing will be auctioned if the amount of 85L is not paid immediately. I felt dizzy and almost unconscious in reading the notice, next morning I went to the bank to see the manager. But to my surprise, old manager was not there and the new manager told me that I signed the documents for guaranteeing the already availed credit facility of M/s SAS Tradelinks. I was trying to get in touch with those people involved in this but all my attempts went in vain.They asked me not to file case against them in police station as it may further delay the repayment. Then I got registered notice from DRTC, up on getting this I filed petition against them in JFMC as well as DRTC. Both cases are going on, shall I have a chance to win this case? Prior deed of property is still with me, I signed the affidavit for obtaining loan not as guarantor,I have proof(News paper cuttings, FIRs) against this nexus in similar cases.
