G4S security selutions

I was at Wierda Glen Estate Centurion East Gate entrance today, were the security officer said he wants to teach me a lesson .Such a blatant act of rasism i have never experiance in my life. It is disgusting and a reflection on G4S security. I just wanted to excit the premises. And was forced to wait 15 min to excit, and was verbally abused, with clients that was with me , security officer John was the instegator. Await your quick response
