Racial Prejudice & Bad Service at AVIS OR Tambo

I picked up my rental around 19:14 - 19:20 from the ORTambo Avis branch and a Lady by the name Lauren was the agent assigned to me. She was incredibly rude and seemed like was not interested in serving me. She reviewed the dates that my insurer had booked me the car for and immediately approached a colleague of hers who were helping a group of Indian gentleman and suggested that she would much prefer that they received the Polo TSI and that I was more deserving of a Polo VIVO. In absolute shock and horror, I remained silent as I attempted to process this inexcusable behavior that I interpreted as racial prejudice and no mutual respect of all clients irrespective of race. My rental agreement nr is available on request. I would appreciate it if AVIS deals with this matter with haste and decisively and make this right as I also use AVIS in my personal capacity and would hate to learn that AVIS tolerates this behavior from their employees. Lauren was unrepentant, unapologetic and displayed an attitude that she had some sort of protection even in the event that this incident was reported. I am perturbed at having experienced this!
