Problem with a lender or other company charging your account: Checking or savings account

I am submitting this complaint regarding the handling of a fraud claim by Navy Federal Credit Union. I reported an unauthorized transaction in the amount of $1800.00 that I did not authorize, initiate, or benefit from. This transaction is inconsistent with my normal spending habits and account activity, and I reported it as soon as I became aware of it. Navy Federal denied my fraud claim, but I do not believe the decision accurately reflects the facts of the situation. I have consistently maintained that I had no knowledge of or involvement in this transaction. I am concerned that the investigation may not have fully considered the circumstances surrounding the charge. I am requesting a review of Navy Federals handling of this claim, including the basis for the denial and whether the investigation complied with applicable consumer protection requirements. I would also appreciate assistance in obtaining a fair and thorough review of the disputed transaction. Thank you for your time and consideration.
