Probably you have the wrong Country / Billing / Shipping Address in the Apple ID. This should be the same as the issuing Bank Country.

Log in to https://appleid.apple.com with your Apple ID credentials.

Scroll Down to the Payment and Shipping Section

Tap on Edit

You will be given both Billing and Shipping Addresses to edit.

Based on your country of residence and country you have selected under your Apple ID --> Payment methods that you can use with your Apple ID - Apple ...

Have you a Debit/Credit card that is issued to you that is valid internationally and is from the same Country / Region as your Apple ID.

Know it here --> If your payment method is declined in the App Store or iTunes ...

Check the following

1. The payment method that you are adding is of the same country as that of App Store Country on your iPhone
2. You have a valid payment plan debit/credit card from an authorised bank from the same country
3. Payment methods that you can use with your Apple ID - Apple Support

For Financial Assistance, Contact Apple Support:

You need to contact Apple Support Directly. This is a User-to-User forum. We are all volunteers. So, as you may suspect, no one here has access to that information — and that is a good thing, BTW. That’s why for Financial Assistance, you need to contact Apple Support. They’ll see what’s going on and will run you through the fix.

Apple Contact Info:

• Contact Us - Choose Locations
• Proceed from there, as necessary
• Why the Wait: Phone calls are taking a bit to go through at the moment, due to lots of calls. With the Coronavirus Pandemic, many are at home at the moment, with much time on their hands to contact Apple. So, just stay on the line, and you will get through :)

Not Relocated?

Call Apple Support:

For Financial Assistance, contact Apple Support. We are not Apple. This is a User-to-User forum.  Apple barely reads these forums as it is. So, call Apple Support. Inform the Apple Rep of what is going on here. They’ll see this from their side of the call and will run you through the fix. Apple would likely see thing in your Purchase History. If need be, perform a Screen Sharing Session with the Apple Rep.

Apple’s Contact Information:

• Contact Us - Choose Locations
• Proceed from there as necessary
• Note: Phone calls are taking a bit to go through at the moment, due to lots of calls. And that makes sense, because with the Coronavirus Pandemic, many are at home at the moment, with much time on their hands to contact Apple. So, just stay on the line, and you will get through :)

Screenshare with the Apple Rep

To easily show the Apple Rep what is going on here, request a prompt for a screensharing session with the Apple Rep. That will allow them to see this firsthand, and upfront. Show this user through screensharing your Mac. Show them any paperwork or hover over something, through screensharing your iPhone.
