Unable to change App Store country/region
iPhone 11 iOS Version 18.0.1 won't change App Store from Australia to Switzerland?
Attempt 1: iPhone -> Settings -> my name (Apple Account, iCloud and more) -> Media and Purchases -> View Account -> Country/Region Australia -> Change Country or Region -> Switzerland -> Agree -> PAYMENT METHOD -> Credit/Debit Card -> International credit card registered in Australia entered -> error: Credit card number does not match credit card type. You have not completed the entire form.
Attempt 2: Browser -> account.apple.com -> something about changing country without selecting payment method (selected None) -> changes to Switzerland -> try to download a Swiss app on the Swiss Apple Store and error: Account Not In This Store Your account is not valid for use in the Swiss store. You must switch to the Australian store before purchasing. Change Store or Cancel. -> Change Store takes me back to the Attempt1 steps with the same circular error.
Attempt 3: Browser -> icloud.com -> log in -> shows no options to change Apple Store country.
Attempt 4: Browser -> Apple support -> chat support encountered the same errors and suggested to call.
Attempt 5: iPhone -> called Apple Support on 0800 001 853 and 0800 801 078 and fails to connect.
Attempt 6: Browser -> Apple support -> chat support no longer available, only phone 0800 801 078 which fails to connect.
Attempt 7: would like to book a Genius Appointment in store, but unable to contact Apple via Chat Support or call 0800 801 078.
Attempt 8: unable to register a Swiss credit/debit card until downloading the online Swiss bank app, which is only on the Swiss App Store.
