Unprofessional behavior

I thought that when we send a child she/he will feel safe and protected but ive been getting disappointed with Aquadene Secondary School(Richard's Bay-KZN) teachers are bulling students today the teacher ask my child to take off the school jersey on 15decrees weather while writing exam how can the child concentrate in exam room while feeling cold probably saying it's not school jersey bt she has been wearing that jersey since grade 8 and dis is 3rd year the teachers are so evil "Mr Hlongwane" department of education needs to intervene dis behavior is not exceptable it's like they dnt have children of their own cause even principal take their side.
