Rude staff at Avis

I arrived to the most rude front staff/supervisor at AVIS Or Tambo. I booked a car from Avis 3 days ago. I did not get the specified car. Supervisor at OR Tambo first his name was Philani. When I said I’ll report his rude dismissive behaviour he said his name is Siviwe Ngxabazi. He dismissed me told me to go. I left with no car. Disappointed at the poor customer experience and don’t care attitude.
