Bp rivonia petrol ****

Hi I would like to complain about BP Rivonia , I poured R100 petrol ULP95 normal when I pour petrol I don’t switch the car off completely because I want to check the gauge as I have been ****** before . I entered the garage with 65km on the speedometer, I left the garage with the same 65km . My gauge didn’t move completely. I wish the was an option to add the photo for the slip . Cause an hour ago I poured the petrol at shell garage rivonia R150 I drove for 30 kilometres only . When they poured petrol the speedometer moved to 120km extra because when I entered the garage I was only left with 7km . This petrol **** happened to me before at Engen in Rivonia also . It seems like Bp and Engen are ******** us on petrol .
