"Can't change Apple Pay billing address: Every time I change my address in Apple Pay it reverts back to my old address. How do I fix this?"

Troubleshooting Updating Method Payment:

Have you relocated? If so, you need to zero-out your balance to make the change. Note that all purchased Apple Store items will be lost, if changed.

Zero-Outing the Balance:

Purchase something that is more than what is in your account. Or, contact an Apple Rep over-the-phone, requesting assistance, asking that they zero-out the balance, then change your location to where it should be..

Apple Support Contact Info:

• Contact Us - Choose Locations
• Proceed from there as necessary
• Note: Phone calls are taking a bit to go through at the moment, due to lots of calls. With the Coronavirus Pandemic, many are at home at the moment, with much time on their hands to contact Apple. So, just stay on the line, and you will get through :)
