My Apple ID has been deactivated

According to Apple Community Specialist Brittany1416 in thread Inactive Apple ID - Apple Community , please contact Apple Support for help with an "inactive" Apple ID.

You can reach Apple Support using this link --> Contact - Official Apple Support

or by telephone at one of the numbers in this support article --> Contact Apple for support and service - Apple Support

Note that having an "inactive" account is not the same as having a disabled account. If your account says it is "disabled", see this article --> If your Apple ID is locked or disabled - Apple Support

● If a message says "your account has been disabled in the App Store and iTunes Store" or "You cannot login because your account has been locked", then you must contact Apple; you cannot resolve this yourself.
