Problem with a purchase shown on your statement: Credit card

I am filing a complaint regarding the handling of my fraud dispute on my credit card account. I reported an unauthorized transaction and followed the required dispute process. However, my claim was denied despite the transaction being fraudulent and not authorized by me. The bank did not provide a clear or specific explanation of the evidence used to determine the transaction was authorized. I requested further details and reconsideration, but the decision was upheld without a sufficient explanation or meaningful investigation of my claim. I am requesting a full review of this case, including : * The specific evidence used to deny my fraud claim * How the transaction was verified as authorized * A detailed explanation of the investigation process conducted * Reversal of the charge and restoration of any related funds or credits This transaction was not made or approved by me, and I believe the dispute was not properly investigated in accordance with standard fraud handling procedures. I am asking for a fair and complete re-evaluation of this case and correction of the account.
