How to change the Country on my Apple account

I sold my house with my apple devices (as they were being used for home automation). Now I am in a different country. I would like to change my Appleid's country. When I click on Country / Region under Personal Information, it tells me >Your country or region can’t be changed right now. When I read the help linked to it, the only two items that relate to me are - Subscriptions (which I have deleted) - Possessing a payment method for the new country (which I do) And it suggests that I should enter a new payment method. --- I tried changing the payment method. The old card had expired anyway. - I entered card details from the new country - I entered the relevant address and phone number for the card - I copied this to the billing address - I pressed Update And it tells me that the card is invalid for the old country.... **Catch 22** --- **Is there a way to Change the Country/Region?** I have read the old posts here on this topic. They are either very old and the instructions don't correspond to the current menu on https://appleid.apple.com/ or they don't have an answer. For example, one of them suggests that you cant change it until you add store credit. But Apple's help says the reveres is true. I have no store credit.
