I've really messed up!

Hello I hope someone can help me!! It's a bit of a long one but stay with me,

I had a client yesterday who's hair I first did 18 months ago when it was virgin hair, I bleached the tips and went over with green/blue crazy colour for a kylie Jenner look. She then had other people redo the green and blue when it faded but I'm not sure how competent they were, not that it was a difficult job or even mattered at that point...

She got sick of the green/blue eventually after roughly 6-8 times...

I've really messed up!
