Can not confirm new e-mail - need to delete

Mistakenly added new e-mail as primary before realizing I could only use one domain on account. Now I can't delete or change back primary email without first "confirming primary". There's no way to do this because domain can not be set up. It's a bit of a catch 22. I just want the newly added email deleted and previous primary email reset.
