I am not able to update my payment information in iTunes the credit card is overdue

Hi mgm9007,

It sounds like you can't update a payment method. We're glad you've joined us in Apple Support Communities, and we can provide some assistance.

If you see a message that mentions a "billing problem" check out the advice in "Find out why a payment method can’t be charged" and "Get more help" in If your payment method is declined in the App Store or iTunes Store. The troubleshooting in this link has the most frequent solutions to adding a payment method. 

If the issue remains after following those steps, let us know if you get an alert and the exact wording of the alert you're seeing when you try to add a payment method.

We hope that helps with your question and take care!
