Can't purchase on Apple Pay

That’s no Apple Pay, it’s your Apple Account. You need to contact Apple Support and get your account straightened out. No one in Apple communities has access to your personal or financial information.

If you’re in the US, please call  1-800-MY-APPLE, or outside the US, consult the support articles below. In Canada, call 1-800-263-3394.
