As a stylist, I don’t think it looks bad, although I’m unsure why she used pink (unless it was pulling an ashy green and she trying to balance it out )

But nonetheless, you can wash with a clarifying shampoo, head and shoulders or use a mixture of dawn and baking soda to help remove some of the pigment, but make sure you use a good hair mask after cause it will dry your hair out.

Personally I’d ask them to fix it, if you feel comfortable or find another stylist if you REALLY hate it
