HELP !!! FERIA DISASTER

Please let me know what I can do to fix a Feria Highlighting Disaster! I highlighted my hair, it is blonde on top with a few medium brown strips. Tried to highlight the roots and they turned out ORANGE & Brassy  on top of my white at the bottom it is so embarassing and I cannot afford to spend a million dollars fixing it usually I have never had this problem but of course I was an idiot and bought another Loreal product than the ones I usually use... PLEASE HELP... Ultimately I want to go all blonde again so I would prefer to not go darker...
