Blonde to Red to Orange Platinum

Ok....deep breaths....I have naturally dark blonde hair that I have been getting highlighted with lighter blonde highlights for several years. I have been very happy with the results. The other day I went in for my highlights, and my hairdresser said she wanted to also put in lowlights to bring out the blonde more. I said ok. Well, the lowlights were severe, to the point I looked more brunette than blonde, and in bright light the brown looked like deep red. She knew I wasn't happy with it and told me to call her the next day if I wanted her to change it. I did. She supposedly reversed the lowlights, but now the dark lowlights are replaced with really light bleached-blonde looking hair, and worst of all, there are some orange streaks in it! On top of it, I have roots exposed from the original lowlights she put in. What a mess! I feel rediculous. I am embarrassed to see anyone I know. But I don't know what else I can do to my hair without ruining it. It is way too light for me, orange in spots, and I don't even think I have any of my original hair color left anywhere on my head. Is there anything I can do???
