Undelete Apple ID

From the article below.

What happens if I change my mind after I have requested that my account be deleted? 

While your request is being processed, you can contact Apple Support with the unique alphanumeric access code you received, and we’ll help you cancel your request. After your account is deleted, Apple can't cancel the request, reopen your account, or restore your data.

I started the process of deleting my Apple ID and now would like to undo that.

If the deletion request has completed, deletion is permanent, irrevocable, and irreversible.

If the deletion is still in progress, see whatever mail message was received about the deletion.
