Fuel price ******* .

Hi people please check the price of diesel 10ppm at Sasol garages because I think its a ******* being charged 40 cents on a litre more at another Sasol garage with the same fuel .I filled on 11/ 05 / 2018 at Goldreef Sasol R400 at R 15,32 a litre and the following week on 19/05/ 2018 I filled at NewMarket Sasol in Alberton R300 and the 10ppm diesel was R 14,92 litre what a ******* .I contacted Sasol head office but no answer fro them .
