Abuse by Servest Guards at Route 21 Business Park

I have never been spoken to so poorly as I was at the Route 21 Corporate Park, Centurion when I was waiting for a vehicle behind me (WHICH WAS WITH ME) who was providing driver licence, I was far left, and was NOT obstructing any traffic. The guards on duty aggressively raised their voices to me, to move my car. The senior manager on duty, who was upstairs SCREAMED at me telling me he is going to block me when I exit......When I wanted to leave the premises I was blocked and had the senior manager screaming in my face, waving his finger at me. This abuse I believe was a racial attack and unjustified hatred.The mandate of Servest South Africa is to be protecting people, not abusing or taunting them. UNACCEPTABLE!!!!
