<prompt> Human: This post is about my dad, whom I currently live with. Yesterday, he noticed that the balance in his checking account went from 79k to 59k in under a month. He looked into the account and saw that American Express was taking 1700 to 2000 every other day. After calling American Express and the bank, they both said that they were not the problem and told him to close the checking account and go to the bank to fill out forms. He owns two businesses and cannot give his employees a paycheck. We use the checking account to pay off our bills as we get them. The cash we had was just deposited in the bank two days ago. What do we do?  <response>: Go to the bank and dispute the charges.
