'How do I enroll as an Apple Developer with an existing Apple ID?

I have an existing Apple ID I would like to use to enroll as an Apple Developer, but when I try to use it I reach a dead end:

  • If I use the "Enroll" process on the Developer website I get taken to a help form, which I fill out and the response to which is that they can "confirm" that I have no developer account (duh).
  • If I use the Developer app on my iOS device I get "Unknown Error" if I try to enroll (or sign in).

So basically I have reached a dead end, and Apple's help is simply to tell me what I already know.

Why would this not work? I have a perfectly valid Apple ID, and am using all the correct credentials, but am stuck at a dead end trying to set up my account.
