Deficiency in Banking services

Good Day all, A fraudulent transaction of 118/- rupees for duplicate passbook / statement took place on my SBI saving account at a non home branch in some other state. Filed complain for same and requested for documents which were furnished to get those documents but bank dint provide anything. when personally went to branch, was told these documents may be filed somewhere else as record keeper is not that educated and once they find my documents will inform me, but still no response but bank showed me the CCTV footage for that day wherein i identified the culprits. After waiting for a month, Finally i filed a case in court under sec 156 (3) IPC 420,467,468,471 and 120 B against culprits including the bank manager of that branch where this incidence took place. Now recently i got an official letter from that region admin office stating that there was no duplicate passbook / statement was issued.....it was some 40 entries which were done in my passbook. Need help in filing case.
