Please help!! Hair dye gone wrong

I got my hair dyed yesterday and this is what I asked for....

But this is what I got....

My hair is BLACK, like Morticia Adams black! I’m absolutely mortified, I look like a gothic teenager 🙈. Not to mention I have a bump on the back of my head from when the hairdresser was slamming my head up and down on the bowl while washing the color out. I don’t know what to do, how can I get this color out??
