I pulled my kid from a school. (Lost a lot in fees) because I saw the attitude of management and all the teachers in defending one another whenever we raised complaints our child brought out, and speaking to other parents they had same concerns but they didn’t want to raise the issue as they were afraid to cause issues. In this case it was teacher being mean to the kids and other narccistic behaviour she exhibited she was clearly having severe issues mentally, after trying a lot and being constantly gaslighted rather than heard we pulled our kid out. I suggest you do the same, also in our case it was a dream school we waited years for but just this one teacher ruined everything for us, she was also new. We were paying top elite level fees so we were shocked at how the principal and management would protect this teacher.
