I wanted to ask you a question. I got my hair highlighted yesterday but I really don't like them

They don't look natural like I wanted them to..I did the Balayage(sp) highlights and are supposed to look like sunkissed highlights but they look like the streaky ones ppl get done. My natural hair color is like a light brown..i also don't like the color of the highlights. So..is there anyway I can get rid of them? Do it myself? I'm really bummed it didn't come out how I wanted them to
