salon color disaster pls help

I had a bad experience with a salon and highlights/color last year and was left with damage so i rested my hair and decided eventually I needed to get it sorted out and cut...so...I went ahead and booked the appointment and when I came in we discussed my colour, the colour that had been on it previously, and the colour I wanted to achieve.

Which was a warm caramel base with warm golden/honey highlights. (Comparable to say Jennifer Aniston)

My hair at that stage was a light golden brown with alot of copper tones particularly on my ends.

the colorist was confident she could achieve what I had asked for and said she would go for a subtle result as she wanted to take care of my hair. I was happy with that and told her if I needed to have a second lot of highlights then that was fine.

She agreed and acknowledged what I was asking for.

At no time did she say it wasn't possible. She mentioned toffee,caramel,golden in our conversation, I felt we were on the same wave length.

She also discussed neutralising the copper/brassy tone on my ends. I said that was fine as I trusted her as long as we got the result we'd discussed.

I was happy and realistic enough to know that colour correction is not easy and we may not get exactly the results desired first try but that we'd get close.

I said this to the colorist and she said she'd get very close and that I may feel I neded more highlights, but that was it.


She did fine highlights and put a semi permanent in between. She left me to process. I told her my hair processes fast. She checked my highlights once for me.
After I was toned and rinsed,
I was concerned as my highlights were white and my hair underneath was very dark brown.

Much darker than my natural colour (which is a warm golden dark blonde.) and much more ash toned.

I complained and she toned the highlights a golden color but they're still very white and my base color i was told would fade up warmer! it has a tiny bit but its still too dark...what should i do...i've complained again...and they've offered to have somoeone else fix it...i'm really upset and don't know what to do now!
