Credit card or prepaid card — NAVY FEDERAL CREDIT UNION (PA)

Card was charged for something you did not purchase with the card. On XX/XX/XXXX. I got a notification from my navy federal credit union credit card for 3 purchases 1. XXXX XXXX for {$200.00} 2. XXXX for {$39.00} 3. XXXX for {$4400.00} I was out of town for most of the day on business. I contacted the bank on XX/XX/XXXX to make them aware of the fraudulent/unauthorized purchases on my card. They finished their investigation and told me that they did not see any fraudulent activity. I put in a request for a second dispute review on XX/XX/XXXX because I knew something was wrong because I dont make big purchases. And when they did a second review they denied it again.
