To access an Apple account when the ID has been disabled, contact Apple support online at Apple.com to determine whether a security issue exists that may affect purchases or downloads. You can also make an appointment with a local Apple retailer to reset the ID or troubleshoot the device.
You can make an appointment on a mobile device by using the Genius Bar app or by calling a nearby Apple dealer. If your account has been disabled for reasons other than security risks, you can reset it using the iForgot feature from Apple. The iForget feature requires users to answer a security question or authenticate the ID with an email account to reset the account.
