apple ID has been deleted, what can i do to reinstate it?

If your AppleID was deleted at your request then there is no way to reinstate it. Deleting an AppleID is a permanent action.

For information relating to 'How to delete your Apple ID account', click here --> https://support.apple.com/HT208504

If you see a message that says "Your account has been disabled in the App Store and iTunes" or "You cannot login because your account has been locked", click here and read what to do ➞ https://support.apple.com/HT208856

Read the support article "If your Apple ID is locked or disabled"; it has solutions for two frequently encountered reasons for an account to be disabled/locked. Click here --> https://support.apple.com/HT204106

I know there's some redundancy in the documents but apparently I need to post both here because not everybody is aware of that.

This should help clarify further.
