So another update from the data controller, they sent an email very soon after the last one, saying it had been sent in error and to disregard it.. ha

So in the updated reply they say:
"We can confirm that, with few exceptions, the payment processor for FFXIV will accept any debit/credit card and does not require updated address information to process payments. As such, your current address not matching the 'country of registration' should have no effect on your payment being processed."
This has left me scratching my head. I've not run into payment issues myself yet as my card was added on the old payment system and my sub hasn't come up for renewal yet (and I'm too scared to pause it). But then where are the issues coming from if they say there is no issue? Is there only no issue in EU?

Can people confirm if they're still getting invalid address responses and the region they're in?

They also confirmed the personal data being used by the payment processor:
  • Payment card information
  • Name
  • Contact information
  • Billing address

As country of current residence is never data captured by them, there is nothing to be rectified on their end.

Not sure where to go from here honestly..
