Pick n pay staff insulted my daughter

Hello Peter I'm not happy about pick n pay at Tembisa mall, my 13year old daughter had energy bars in her backpack she forgot to tell the security at the door when entering the store, on her way out they searched her and found them while she tried to explain to the security guard that she got them from her father, then a lady who works for pick n pay started insulting her and calling her a ***** then my daughter called her father so he can explain that he bought dose for her the lady refused to listen to him, what makes me angry is that she was insulted in front of her school mates how will she be treated at school after this, she feels humiliated
