Settlement of personal loan

File a grievance petition to the Chairman stating your past record before undergoing surgery, and your disabilities after surgery, position of your assets and income with such documentary evidence, hope that the petition may receive humanitarian consideration by re scheduling.  (They may take a chance asking you to repay the compromised amount in full, and after one month they may (???) sanction you that amount which has been repaid with longer duration of EMI.

I am afraid that you are not coming with facts, as a bank can not file suit when there is no chances of recovery and files only when they have certain valuable asset which may deteriorate the value in case of delay.  It is too late now as a suit was already filed.  You may also file a petition to court for referring the case to LOKADALAT for working out chances of compromise.
