How do I close my free account!!!

I attempt to close it and I get...

You are an administrator of your organization : "blah blah blahl". You should cancel your

organization from Business , before closing your account

What's business?

I don't have an organisation

I don't have a domain anymore.

Why have you made it completely impossible to close an account? it makes no sense it just winds people up, if you want repeat business tell me how to shut this thing down please.
