What is the expected UX behaviour when you delete your account from a service?

The "Delete account" option in our product is really just a unsubscribe from the service option - the user is still able to login to the system but no longer has access to the actual service.

My question is: What should happen once the user selects 'delete account'?

  1. Show a message that their account was deleted?
  2. Logout the user immediately?
  3. The screen that hosts the "Remove account" option changes so that there is no longer an option to delete account and a message is displayed that the account was deleted?
