Q: Billing information in Photos doesn't match Apple ID

The credit card that Photos has on file doesn't match my Apple ID.  I've updated it in the Photos > Print Product Store Account and double-checked that my Apple ID is using the right credit card.  However, when I go to buy my photo book, it's pointing to an old credit card that I can't use.  It's been a week since I updated the Print Product Store Account billing information.  What do I need to do to get it updated?

I've also been trying to contact Apple support through their website.  Support is timing out.  Anyone else having this issue?
