Got lost when moving country
I used to live in Canada, and have recently moved back to the US. My charge card was registered to my Canadian address, but has already been changed to my new one in the US. With Apple’s Canadian services, I hadApple Music with a family group, which expires in three months. Now I can’t change my card details because of that, nor my country of residence. In the meantime, I’ve lost access to my music library, can’t make purchases from the App Store, and Apple Support can’t help. What should I do? Apple’s instructions are at bit.ly/leave_familysharing and bit.ly/changeregion. You must first leave the family group, even if you’re its organizer, although doing so will dissolve the group.
Once you’ve done that, you should wait for your subscriptions to expire. Just before that happens, download all of your past purchases, then change your country of residence and payment card details.
Of course, this all assumes an ordered and planned process, which you have not been able to undertake. Although you can leave the family group, you’re already unable to download past purchases, and the change in your card address seems to be blocking you from changing any of the other details for your account, in an effort to reactivate it.
There doesn’t appear to be any way that you can circumvent this chain of processes now. The only way that your account can be put back in order is for Apple to step in. Keep trying with Apple’s iTunes Store support, in the hope that someone there will escalate your problem to a member of staff able to rectify this.
