Overfilling/overcharging

<p>Good Day Sasol.</p> <p> </p> <p>Today I filled up at the Sasol Service station in La Belle Road, near Bottelary road in the Western Cape. My car takes 50 litres of fuel. When the fuel light comes on and I have driven for a while with said light on , other garages only manage to squeeze 51 litres into it. Today you put 60 litres of fuel into my car, which still had around 10 litres of fuel in it when I filled up.(according to trip computer I had 150km left.) Which means my car now has a 70l capactity according to you....This cannot be right. I have the slip which clearly indicates 60L.</p>
