for the money, you can call bank and explain to bank about what happened. Bank will still not give you details of the person who bank in. Cause bank have to keep customer details confidential. However, you can tell the bank to contact this person to call your number. This way, you are giving the bank authority to have that person call you. This will work as I have tried before. This method will not hold bank responsible for anything as it does not break any P&C code by the bank.

second, you need to play along with the scammer. A lot of things can be done. Whether you want him arrested or beat up or so on. I think you should be smart enough to figure this out. Good luck.
