Worst service EVER!

I stopped in the pickup zone to collect an important client from the airport on the morning of 08/11/2019 at 06H40 in the morning (Cameras will verify). I existed my car and walked to the front door to meet and greet the client who flew in from Durban and walked back to the car to find the vehicle clamped and a note stuck on my window demanding I pay R500 to release my car. I asked the security guard what’s going on to get a reply from him he woke up this morning to see how many cars he could clamp and laughed at me. I then tried to speak to the so called attendant at the office to explain I did not "park" the car but I was there to pick up a client only to be told I must pay R500 to release the car. I tried to explain what the reason was but I could see the aggressive attitude in his body language sitting there with his arms folded. His reply was I must read the seven (7) singes in the pick-up zone that it’s not a parking. MY POINT EXACTLY, I WAS THERE TO PICK UP A CLIENT!!!!!! I asked to speak to a manager and was told to speak into a phone (He didn't even have the manners to come out and attend to my query in person). The parking manager was rude and after trying to plead why I was there eventually he lowered the "penalty" fee to R135. R135 rand to meet and greet and important client at the door? Then they say they want to become a world class airport??????????
