hacker disabled my apple id

Someone may have mistyped their own ID, you don't know this was an attempt to hack your account.

When your account becomes disabled, Apple provides the following recommendation:

"This message means that someone tried and failed to sign in to your account multiple times. The Apple ID system disables the account to prevent unauthorised people from gaining access to your information. You need to reset your password, following the instructions at the Apple ID website".

Visit iForgot.com and follow the instructions there.

If on the other hand your message simply states that your Apple ID has been disabled, you should contact Apple ID Support and explain your Apple ID has been disabled.

See this article If your Apple ID is locked or disabled - Apple Support

You might want to consider doing a name change since they know your Apple ID.
