I tried to chat with them but I faied to find it in their website. Actually I haven't used any apple service amd device since 2022, so I don't think I have any subscription.

Anyhow, can you advice me how to chat with apple care team ?

Here you go:

Contact Apple Support - Apple Support

Additional info for changing your region is here. The region of the financial institution for the added card must match the region you have on your device, otherwise it will not work.

Change your Apple Account country or region - Apple Support

Hello~ In addition to *Mac Jim ID’s* always helpful information…

Add a payment method to your Apple Account - Apple Support*

*If you can't add a payment method

• Check what payment methods you can use with your Apple Account in your country or region.
• If you're using an accepted payment method but your Apple Account is set to a different country or region, change your country or region.
• If the Add button is grayed out, you might be in a Family Sharing group and you use purchase sharing. Only the family organizer can have a payment method on file. If you want to use your own payment methods, turn off purchase sharing, then add your own payment method.
• Double-check that your name, billing address, and other information is spelled correctly and matches what you have on file with your financial institution.
• Some payment methods require that you verify through your financial institution's app, text message, or other means. Contact your financial institution for help if you're unable to verify.

Do you have any ongoing subscriptions on your Apple ID? This could be the issue. Best course of action is actually chatting with Apple Support, they can tell you what the issue is.

Personally I’d try calling them in that scenario!
