You will need to use one of the support links below. The primary option (telephone support) under the Apple recommended support link below has not been consistently available recently. It is not available now. (2:41 pm) So if it is not working properly when you need it, then use one of the other support links I posted below to contact Apple support. 

See If you see a message 'Your account has been disabled in the App Store and iTunes' https://support.apple.com/en-us/HT208856. This link says: "There might be a problem with the payment method that you have on file. When you see the message, don't try to edit any of your account information. Instead, contact Apple Support for help.”

Try using the Apple recommended support link above first. But, this site is down/not fully functional very often. Use the support options I give below if necessary.
