Updating credit card information in itunes
A card that you previously had no trouble using to purchase apps, songs, or movies will stop working and the App Store simply tells you ‘Your payment method was declined’.
It then asks you to update your billing information. If updating your billing information doesn’t fix the ‘Your payment method was declined’ error, you’re at a dead end.
The App Store and i Tunes doesn’t provide any further direction but here are a few things you can try.
Try purchasing the app or paying your subscription from i Tunes. We assume you’ve already updated your billing information once and it didn’t work.
Sometimes, that can get a little overwhelming and you may want to shut that down.
To see that, you'll have to log in via i Tunes on your computer.
Most people are not going to need more than one i Tunes account assigned to a single i Phone or i Pad. You may work somewhere that the company wants you to use its account to download apps to your device, but you also want to use your own apps.
