Galaxy account dot trouble

Hi,

I have old account michael.heca which is linked with github. Account with dot are unusable.
I create new account orgoj, linked with github. But login with github, log me to old michael.heca account.

How to change github link, or delete whole old account with dot?
Galaxy is now unusable for me.

Thanks

Michael Heca
