Msimango

My son has been in Primrose Hill Primary since 2010, when he was in Grade R. He used to talk about teachers hitting children but I would never do anything about it because they don't hit him. One day when he was in grade 2 I saw that something was wrong and I asked him, he told me he as a headache because his teacher hit him so hard on his head, anyway I phoned the principle Mrs Van Vliet the next day and she immediately started defending the teacher, anyway I could see I'm not getting anywhere with her and then I decided to go see the the teacher myself and warned her not to touch my son again. Second incident was last year when he was in Grade 5, I used to hear about this one maths teacher who beats up boys even before he started teaching my son. Anyway then my son came and told me that he punched in his waist and I then reported it to the teacher and he phoned me and apologised. Third incident which is the latest incident, this Mrs Msimango is calling my son bad names and he passes her subject so well, and the principle is being extra unhelpful this time, and I don't know what to do.
