Why does it say deleted, when in fact it still exists?  If I have a customer with zero transactions, and zero invoices etc.. there is no way to delete them from the system.  As a developer it is some what annoying that I can't simply delete it using the API or in the UI.  I am sure you have your reasons, but for God's sake, change the language to what it really it is - inactive.  No deletion is possible.  Unless I am wrong?
