With these other workably good suggestions,
to round them up with this, seems proper:
• Check your Apple ID balance - Apple Support
//support.apple.com/en-us/HT202359
• If your Apple ID balance seems incorrect
• If you plan to delete your Apple ID or change your country or region
• If you have Apple ID balance that you can't use
[Each of these sub-topics offers ideas on what to do.]
First suggestion: 'Get Support ' above-all, is good!
