Business ProfileforFirst Credit Union

I had 2 fraudulent charges on the credit card I have through First Credit Union on February 17, 2024. One was refunded and believed as a fraudulent charge the other was denied as a fraudulent charge and I am being held responsible to pay a charge I did not make. Because they made the decision that my charge was legit I am being told there is nothing else my Credit Union can do about it. I contacted the business who made the charge and they also stated there isnt much that can be done. I have been a member at FirstCredit Union since the 1990s when it was called First Federal Credit Union. What is the point of fraud protection if they are not going to believe you if you have fraudulent charges? Why believe one is fraud and not the other. I also attempted to contact ***** however they were not helpful either. $359.94 is not that much, they should just refund me. The merchant admitted the phone number used to purchase tickets was different than mine. I have uploaded a picture of the individuals who charged fraudulent charges on my CC that was mailed to me from First Credit Union. I do not know these people and I did not give them permission to use my CC.
