Mistreated by a security guard who works for Riskcon Security

Today at ackermans west street my shopping was a nightmare.I went to shop for a baby shower gift whiles shopping my phone rang and I placed the clothes that I had picked on top of a clothing rail in front of me. I then opened my bag and reached for my phone as I closed my bag a security guard by the name of mthokozisi myeza approached me and ordered me to open my bag at that moment I was confused and asked ,do u think I stole something? he did not answer and brutally searched my bag. He did not find anything he than grabbed the clothes I had placed on the rail and ordered me out saying people like me are not needed in the store, I stood there humiliated and angry that I responded saying I am not going anywhere , he then turned seeing that I was not following him and came towards me and said are you buying this"refering to the clothes I had picked"I said yes, he then ordered me to go to the cashiers and pay right away... Mmmh I then told him I'm not done and I am waiting for a friend who is going to help me shop for the baby shower gift,he then shook his head and said I must get out of the store and if I have a problem I should see the manager. In the mist of this all the manager a lady by the name of pat approached us ,it was now a big scene because me and the security guard were going back and forth arguing. The manager approached us and asked me what was the problem I told her everything, she then apologised and asked the security guard to apologise but he refused and said she must call his manger(security company's manager) he is not doing that, then a random lady /customer who had witnessed everything approached us and said she saw everything asked the security guard to apologise but still this guy had alot of pride and refused. I then walked away and told the store manager that I will lay a complaint the store manager was so helpful and also shocked at the guards behavior...... I have never been so embarrassed. This guard needs to be disciplined
