Procedure to open under protest account before filing suit

I want to file suit against Nationalized bank, but before that i want to open an account "under protest" and deposit entire outstanding amount. .I therefore require correct procedure to open this account. The bank has declared me as an absconding person and a willful defaulter, as i met with an accident & was bed ridden for some time, This was revealed from their own communications with their head office. This fact came out since I filed RTI applications. During my illness, the agent from bank manager use to visit me for bribing against settling of my dues. Your assistance will help me a lot.
