Same for me GreeceTried with 3 different accounts and a number of different credit cards successfully purchased a random app from app store but every enrollment request keeps getting canceledApple support stopped responding to any requests after the firstIn that first response they informed me that their payment system do not require either the card security code or a passcode from the bank to work, dont see how this is possible and that I should supply them with order details from my other purchasesNever got a response back after thatI have created a post in Hacker News about this in order to raise some awareness https://news.ycombinator.com/item?id=23311675
