Complain about poor customer service in Azure total petrol station in mpumalanga

I went to Azure total garage I Mpumalanga at about 17h00 on the 5th of April 2023 to fill fuel in my car, which is a pegoet FZZ 307 MP. I was in a que waiting to refill on other side a white bakkie came and waited on the que, a petrol attend by the name of Sibusiso went to the driver of that bakkie who was Indian cause the other side was empty and ask him to go go fill in diesel, actually he gave him special attention. I saw that the side was empty I drove there park and he Sibusiso came to me swearing so loadly calling me names. I told him I came first before the Indian guy but he shouted and told me how mad I was in my head and how I don't listen, he was trying to impress the Indian guy in my expense and to show his fellow workers that he does not care about customers. I was so very disappointed at the poor service that I got there, I asked for the manager but they. told me the manager was off. I was going to rate zero but this system doesn't allow me
