Hi Lukaa111,
We want to help you with updating your payment method, and we have steps posted below to help.
Try following these steps for a failed payment method:
- "On your iPhone or iPad, open the Settings app.
- Tap your name.
- Tap Payment & Shipping.
- Add a different payment method and remove the old one.
- Try to complete your purchase."
If your payment method is declined in the App Store or iTunes Store
If you're still not able to get your payment method added and purchase completed, contact the Apple ID experts here:
Thanks for using the Apple Support Communities.
