I think I got scammed by a fake Verizon number, and I’m wondering if I’m just out the money

The user called a fake Verizon customer service number, leading to unauthorized charges on their Visa debit card. A $255 charge was declined by their bank, but $336 and $730.30 charges went through before the scam was discovered. Verizon incorrectly confirmed the number was legitimate, and the user disputed the charges with their bank.
