Brown Red Wig

I went to the hairdressers to get my hair cut a bit and they kind of forced me to get highlights done, and I couldn't stand having to be rude and accepted. But first I asked them, what will it look like? And so they showed me a picture of a woman with nearly the same hair colour as mine without the redness. The woman in this picture only had a tiny bit of highlights at the tips of her hair (and only a few strands). So they said we'll do the same as this. I told them I had to meet someone in an hour so how long would it take. They said 30 minutes. I accepted. 2 hours later, they had covered nearly my whole hair, and were still working on it.

Anyway now I have ugly yellow stripes down my hair. And it looks very ugly. They charged me a lot of money aswell.

What can I do to my hair? Please help, it looks like I've got a red and yellow wig on. My beautiful hair's gone!

Thanks!
