The Hair Exchange

Never again will I go back and give them my service, asked to get my roots done (I have blonde hair) she couldn't do it so I tried making it easier to her and tell her to give me an ombre instead, all she did was put a light brown on my roots and dragged a bit down to my ears.. Now the brown she put in turned my whole head a tinted green. The next day that I went in to complain she was very rude and unprofessional as she argued with me and blamed me for "changing my mind" to many times. She's the owner and the manager but can't even do a good job?
