Bad Mannered

I was called in morning by the Deputy principal , I forgot her name she spoke to me regarding my Son's behaviour she was very polite and humble, I called back again asking to speak to Mr Lawrens his secretary or PA was dropping a call in my ear, one last more thing that irritates me worse is the way Mr Sali spoke to me telephonically, I do not appreciate his tone he was very rude , I was asking to speak to speak only to a Principal and Mr Mpisa ,I was only requesting a footage from the principal of the school and the side of the story Mr Mpisa ,that might happen what my Son is telling me is not true. How Mr Sali spoke to me I do not appreciate it he was rude and shouting at me I'm not a child or my Son that he can speak the way he wants.
