Managing an account: Checking or savings account

I filed a fraud claim with my Capital One, but the bank incorrectly filed the claim. So, I called the bank ( phone call # 1 ) and was given provisional credit while the conducted an investigation, but due to the filing error my claim was denied and the credit was then taken from my account. I called a second time ( phone call # 2 ) and the same issue happened again or was not revised from the first call. Therefore, for a second time, my claim was denied and the provisinal credit that was provided while the investigation was taking place was taken from my account. I called the bank a third time ( phone call # 3 ) and was told the second claim was denied. In every phone call no reason was given for the denial. I then asked for a supervisor who informed me and admitted to the fact that the bank filed my claim incorrectly. He explicitly said so and apologized during a recorded phone conversation. I now have a negative balance with bills pending.
