Assming that you mean the website, then you are right. That is a bit weird TBH. I've never noticed as I can delete accounts (including my own) as I'm an administrator, but I just tested in a non-admin account and I can't find it anywhere. So that's a bug in my opinion.

So I've just triggered an account deletion for you. It requires email confirmation (i.e .check your email and it should contain a link to cancel your account). Please post back if it doesn't work.

Also, if you have any feedback for us. I'd be particularly interested in hearing why you no longer want a TurnKey account, but happy to hear anything you'd care to share (good or bad).
