Hello, thanks for reaching out.
You should sign in using the same Microsoft account linked to your previous subscription. Then, go to your payment settings to update your payment method and country. Microsoft supports adding local cards in your current country and will automatically adjust your billing currency. Once updated, you can pay any overdue amount with your new card. If the system still shows only the old card, you may need to contact Microsoft billing support directly for assistance.
