Caltex - Bad customer service

I went to Caltex Petrol station, Victoria embarkment in durban,on Sunday morning 19-06-22 to fill Petrol and the garage had faulty Petrol pumps which took them two bousers to fill R100 Petrol I requested,left for work.when I later was driving the car,the Petrol light went on, showing the R100 Petrol wasn't filled in the car,I called the Caltex Garage,I was told to come in the morning,when I got to garage this morning,The supervisor called JAMILA treated me like a crook that is trying to take advantage of them having Petrol pump problem saying they checked the car was filled and R100 Petrol is not even enough to switch oof the Petrol lights of 1,0 engen Renault kwid,Ended by saying the manager will call me,even now I'm waiting for the manager to call me
