Help!! Fraudulent Charge on Credit Card 💳

💕Briabella • Wife to my best friend💍 ✝️ womanhood💕 She remembered who she was ..and the game changed💋

Hey I need some help! My husband disputed a charge that came on his credit card from a towing service he never used. After disputing the charge, the credit card company is saying that it is a legit transaction! Its a $900 charge and has now impacted his credit score! Any suggestions as to what to do??? Has anyone experienced this before with Capital One.
