Engen - Filling my car tank with air not petrol

On the 10th of November 2022 at around 18:10 went to my nearest garage station which is Rampi ENGEN garage situates in hammanskraal Temba.. I requested the petrol attendance to fill my car with R150 ( 95 petrol) .. their machine did the counting that indeed it filled my car with R150.. but when I switch on my car it shows that nothing was filled, I asked for the supervisor because I know where my car tank was at, but they refused to assist they forced that they did fill my car of which I'm telling them that maybe your tank is empty , .. I had to leave because they couldn't assist me, 10 km away my car was on reserve to show that nothing was filled in my car.. I had to stop to another garage to fill again . . My car is Renault kwid, good at petrol saving... I'm not happy, I paid up for something that I didn't receive.
