Should I ask for my money back or just eat it?

I recently got my hair done at a salon I have been going to for the last year-ish. I went in for the same thing i always do. This time I left feeling like the color was uneven throughout my head, there were harsh lines of demarcation and no root shadow. So I called the salon and they booked me for an appointment to fix. I went, we talked explicitly about what I was looking for. She added more color to even out the color distribution and added the root shadow. But the toner she used blended everything together too much to the point where I’m darker than I was before my first appointment (when I already had grown out balayage).

My dilemma is: do I call the salon and mention my disappointment again to try and get some sort of refund? Unfortunately I no longer trust them with my hair.

Or do I just move on and let it go, spend more money on another salon to get it right?

So torn😩
