Retiring a learner from ecommerce

Hi everybody,
I faced a problem with enabling my edX users to delete their accounts,
I managed to run script from tubular repo but it fails when reaches to RETIRING_ECOM .
in the output I found that it fails when trying to request this URI:
so going further I guess that this api is not implemented yet.
Is that right? Or I have made a mistake somewhere?
Maybe I have to enable that api or what?
any help would be appreciated
