The visa call is suspect. Sounds like phishing.
But the other point is important. Apple Pay virtual card can be changed with a Apple ID password reset. But Apple Pay itself uses another number, not the virtual number, and if hacked, you can’t reset it (or ask for a new card). I think my Apple Pay was hacked when buying delta Wi-Fi in flight. I had several hundred dollar charges each month claiming to be delta Wi-Fi. It wasn’t delta. And Goldman Sachs said I couldn’t change my Apple Pay number. So I canceled. 😔
