How can I remove my user account from an atlassian.net instance?

[jameshartleroad]

I got signed up for an atlassian.net JIRA Service Desk instance and don't want to be on it.  How can I delete my own account and stop the e-mails, since whoever manages the instance won't reply to me?

 You'd need to be an admin to do a full delete.

Personally, as you're not getting any response from the "owner", I'd change my email address to theirs and leave them to get all the spam   Rather passive-aggressive, but they're not giving you a lot of options here.
