Question marked as
To update you payment information Change, add, or remove Apple ID payment methods - Apple Support
About locked accounts
Apple ID If your Apple ID is locked or disabled - Apple Support
iTunes and App Store If you see a message that says 'Your account has been disabled in the App Store and iTunes' - Apple Support
I'd advise you not to deal with it if it isn't clear for you. Just give Apple Support a call and they'll help you get everything in order. They have the proper access to your account to help you with it.
