There is no chance of getting your money back. Even if the Bank is licensed and insured the deposit the maximum that that can be settled through insurance is maximum one lakh.
Govt. Might have already appointed one Liquidator or receiver or some Special Officer. You have to get a working relationship with Employee/Exemployee or some well known depositor of the bank and should get latest position on the Bank.
Depositors also might have formed a joint association to fight out. Such things take their own time and it is better you make alternate arrangements. First send a Registered notice with copies of all deposit receipts and demand for payment of deposits. Then you may receive some information and then you can decide further course of action. Do this immediately.
