Hi apple no idea why my bank details won’t match with my Apple ID seriously need help not happy my card keeps being declined

Hey, Matmufcmad.

I see that you're trying to update the payment method you use for iTunes Store and App Store, but the card information keeps getting declined. I'm happy to help.

If your payment method is declined, or you have a billing issue with a previous purchase in the iTunes Store -- Review the information in this article and follow the steps provided.

Take care!
