Billing Problem

Hi emeka59,

Welcome to the Apple Community.

Your Apple ID is the account you use to access Apple services,

such as the App Store, Apple Music, iCloud, iTunes, iMessage, FaceTime and more.

Apple support can guide you through the steps to update your credit card details.

See the article that opens from the link below.

Change, Add or Remove Apple ID Payment methods

Hope this works for you :-)

Sorry that has not worked for you.

Wondering why not, or if there was an error message that suggests a solution solution.

We are all Apple users like yourself here, so have no access to your account to see what the difficulty may be,

If your Apple ID is locked or disabled: this article may help 

(eg … after entering too many wrong log-in attempts)
