If it is NFET, you can put up charge back and request dispute. You will need copy of atleast police note for the same. Make sure you mention exactly what happened and you should be able to get it. Police will not recover it mostly, it is bank with the help of police fir copy can mediate the dispute.

If you have not mentioned that it is accidental mistake from your side as of now, register unauthorized compromised account transfer which is much easier to deal with and bank will surely help with you that as it is mentioned in consumer grievance policy and RBI makes it mandatory to look and mediate in this case for banks.
