<prompt> Human: So around December of last year, my dad lost his debit card. Due to his illness at this time, he didnt check on his account, so he was unaware he was losing money. However, my brother who is also on the account contacted the bank and requested they cancel the card, which they did not do. My father then looked at his account recently, and found that 13,000 i.e. his entire savings was missing. So, what can be done about this, if anything?  <response>: Have you father contact the bank and file a fraud claim.
