Rasist act of Empro Academy white teachers

There a private school called Empro college at 66 Erasmus Ave Centurion Raslouw, my son is schooling there. Last year one of the white teacher called my son and his friends monkeys. 2023 January the other white teacher called mam Cousin called my son and his friends monkeys. That school is full of rasist white teachers, only 1 or 2 white teachers that are good, the other once doesn't even greet back when you greet them. Only black teachers and 1 or 2 whites are good but the rest doesn't even hide that they hate black people. I already hate that school.
