Billing Issues - Neel from Mauritius

Verify that your credit or debit card is issued in the same country as what your Apple ID account is set for. That should match, else it won’t be supported.

If your payment method is declined in the App Store or iTunes Store - Apple Support

↳ Contact your financial institution about support for these kind of services. Possibly they may need to enable a feature, or you may need a different type of account.

If you still need help after that, then contact Apple Support.
