Deleting GitHub linked account

I would like to delete my account. This seems to be the only way to do so as a GitHub OAuth user. I've already deleted my repositories.

EDIT: I'd also like to add that needing to broadcast this on a public forum seems very counter-intuitive, whether you pay for the service or not. You also end up having to pay staff to do something that should be fairly straight-forward to program and automate.

Hello @williamtheroux, welcome to the forum.
We completely understand your point. We have an open feature request to add this option as an inbuilt functionality in all Prismic accounts. In the meantime, we can continue the conversation in private dm so you can send your account details and we can proceed with the account deletion.
