Why can’t I take my credit card off of my Apple ID?

See if any of the following articles can help:

• Change or remove your Apple ID payment information - Apple Support
• Payment methods you can use in the iTunes Store, App Store, and iBooks Store - Apple Support
• If you can't choose None when you edit your Apple ID payment information - Apple Support

Hi

Go to iTunes main page bottom of page apple I'd click that view I'd Go to manage payments check / change your card details.

If you don't want to use a credit card buy a iTunes gift card redeem at the bottom of iTunes page.

Cheers
