Went and got highlights

Never in my life has my hair ever turned orange. I get blonde highlights every 3 months. Anyways I saw a different stylist. My hair turned orange and they refused to fix it for a week. So I had to walk around with orange hair. Now they fixed it a week ago and my hair is literally falling out in clumps. Idk what to do. It doesn't help I'm 6 mo postpartum and was already losing my hair to begin with but it def has ramped up and more hair is being lost.
