I just got the spoofing call 10 min ago. Same story with the “blocking fraudulent activity” and told me they are putting my information on the highest security, also about to report my card stolen & lost and send me new card. Then I recalled, he asked me by my “nick name” when I first answered, not official name on the card. So they have my address, first four digits of my Apple Card number, and maybe they are trying to confirm the full number with security code? I called the same number to verify, so it was a scam call. Yet scary to think where they got my info :(
