Hey There benfromnottingham,

Take a look at the resource below that explains how to change the billing information on your iTunes Store account.  Are you having an issue with one particular bank card, or any bank card that you try?  There is a link in the article to the iTunes Store Support team if needed.

Change or remove your payment information from your iTunes Store account (Apple ID)

On your iPhone, iPad, or iPod touch, you can change the payment information for your Apple ID in Settings. On your Mac or PC, you can change your payment information from the iTunes Store.

 

When you change your credit card number or billing address through the iTunes Store, you also update that information in iCloud, the Apple Online Store, iPhoto, and Aperture.

Change your payment information on an iPhone, iPad, or iPod touch

1. On the Home screen, tap Settings.
2. Tap iTunes & App Store.
3. Tap your Apple ID. (You might need to sign in with your Apple ID.)
   
4. Tap View Apple ID.
   
5. Tap Payment Information.
6. Change your information and tap Done.
   After you change your payment information, the iTunes Store places an authorization hold on your credit card.

Change your payment information on a Mac or PC

1. Click to open your account in iTunes. (You might need to sign in with your Apple ID.)
   
   Alternatively, you can:
   • Open iTunes.
   • Click iTunes Store.
   • Click Sign In and enter your Apple ID.
     
   • Click your Apple ID and select Account Info.

     

2. From the Account Information page, click Edit to the right of Payment Type.
   
   You can see the payment methods that the iTunes Store acceptsin the Payment Type section. If you want to remove the payment method, select None in the Payment Type section. See what to do if None isn't showing or you can't select it.
3. Change your information and click Done.
   After you change your payment information, the iTunes Store places an authorization hold on your credit card.

Family Sharing

If you’re using Family Sharing, and you're the family organizer, you can’t set your payment information to None. You need to use a credit card or debit card. Only the Family Organizer can edit payment information for a family group. If you're not the organizer, you'll see this message: "The payment method for your Family is managed by [Apple ID]."

Get help

If you need help changing your payment information, credit card details, or billing information, contact iTunes Store support. Or you might find the answer to your question below:

• If you change your payment method, make sure your account information matches the credit card information on file with your financial institution.
• If you use an AOL screen name to sign in to the iTunes Store, editing your information on the Account Information page won't update your AOL account. If you need to update your AOL account information, contact AOL.
• If your previous payment wasn't accepted, you might need to change your payment information.
