Thank you for your reply, and query.
The Apple Community here is composed of Apple users, like yourself.
So we have no access to your account details, or ability too make changes to user-friendliness.
You might want to try this method:
1. Open the Settings app.
2. Tap your name.
3. Tap Payment & Shipping. You might be asked to sign in with your Apple ID.
4. To update the address for a payment method, tap the payment method, then edit your information. Tapping the method should reveal details for that method including the billing address. You might need to enter the security code that's printed on your credit or debit card. If you see Apple Pay after the last 4 digits of the card number, go to the Wallet app to edit the card information.
5. Edit the method then tap Done
Hope this works for you :)
You might want to send feedback on user-friendliness on to Apple.
There's a webpage for sending feedback:
https://www.apple.com/feedback/
There is a "Get Support" link to Apple at top right on this discussion page,
if you need more help with the address change.
All the best :)
