Created group with no member and cannot delete it

I tried to create an organisation on anaconda.org but there was some kind of technical troubles on the website. Now I have created two organizations to which I don’t belong (but I created them) and cannot delete them.

Can you please look up and delete them?
/mbi-div-b and /lunin-org

You can see that I’ve created them in my feed:
