HOw to do you contact a person who operates GENI. Management of the sites

How do you contact the site management.   Is it possible to completely remove my tree or my creating one they have ownership of my tree and informaiton.  When I signed own I did not intend for them to own my informaiton.   What I hate about this darn site is they assume my information is wrong.  I have female in my ancestry I worked hard to fine when, where she died and they keep making others incorrect information correct for her.   This stink along with their grabber ownership of the tree.   I would have never signed up if I know they wouuld have permanent control.
