You need to contact email support and mention that you faced same problem as many other users.Better to provide link to this thread in order to let Apple know that problem is serious.

This problem seems to be major because it refers to many developers. Faced it myself, I conducted inverstigation around developer communities and I have read a lot of developer troubleshoot reports from Russia who are unable to enroll Apple Developer Program because of payment impossibility. Perhaps it applies to many countries except the United States, not only Russia.The problem is not in any bank. Banks keep answering that they did not receive any payment requests, while Apple Support continue answering about problems from bank side with advice check billing information. This is wrong because trying different banks and credit cards did not help.Problem seems to be from Apple's side, in payment processor or security system, probably both.How can we get Apple's attention?Problem is seriously major because many people have issues and unable to make payment for Apple Developer Program since November 2019.

Just the same problem. Different credit cards and none of them worked, banks provide info than no purchases were made.What is goning on? Contacting Apple Support doesn't help.
