Horrible Teacher

I have 2 kids in Midrand primary its a good school with a high passing rate, the only issue is that my daughter who is in in grade 7c17 has been traumatised for almost 1 teacher by the name of ma Khumalo. Apparently this teacher my daughter that am a useless and irresponsible parent when I didn’t show up for a parent meeting due to circumstances beyond my power. It’s not the first Time she’s saying this to my and different another kids in the classroom. Serial times she has been reported by other parents who have undergone the same treatment to the Principal of the school Mr Mulaudzi who has done absolutely nothing about the matter and this had affected a lot of kids in that class. She brags about how her son is more intelligent than the kids in the class. She is very mean and sadly this has affected my daughter’s confidence . If the principal doesn’t make any disciplinary action against this teacher we will escalate the matter to the MEC
