<prompt> Human: My family went to deposit their savings today and were shocked to find that their entire savings account with roughly 50,000 had dwindled to about 4,300. My father keeps accurate records of deposits and withdrawals and never uses the account except for emergencies.We are all freaking out and the bank said they needed some time to investigate. What can I do? Will the bank refund our money?EDIT: Thanks for the input everyone, I think well have to wait until the bank finishes their investigation before we really do anything. Going to find a lawyer in the meantime though just in case.  <response>: No one can possibly know. Wait for the bank to investigate. Money just doesnt disappear.
