Hello, I have same issue. I was asked to send successful purchase from Apple in the past by support. I have sent them, but support ignores me. Then I have send them email asking my previous case, senior advisor reply with "use the latest safari, contact your financial institution, bla bla bla... It was clear that my card is not a problem, I have sent them the proof just like they asked but they keep answering in loop with already made copy paste answers. In my case, support is a joke! I have tried someone's solution from here also, but they did not works for me. I've used solution Apple Developer app enroll link (because in my country enroll button not avail) then next day is canceled. I've used Mac, set payment setting to never require password also got canceled. I've match my Billing info in my Apple ID exactly with the card I was using to enroll also got canceled.

I have same issue and have submitted a feedback report
