Apple Developer Enrollment throws error before authorizing payment, How to proceed?

I am trying to enroll to Apple Developer Program. It throws Unknown Error has occurred before I get the payment request.

First time I even accepted the payment request, paid the amount. But enrollment didnt work.

Second time I noticed that it fails before I even get chance to accept the payment request. I get the request after 20 seconds or so.
