Petrol pump mulfunction

On the 26 08 15 I went to Engine garage in zone 14 Sebokeng to pour petrol, I was driving a ford fiesta 1.4 and I needed only R50 petrol . my car was on 22kl low and after Majola helped me but I saw that the petrol was not going up I then decided to see if I drive maybe it will pick but nothing happed I had to make a u-turn in mosheoshoe street and I approached him and we went inside the garage to the cashier to ask for prove that he did pour the petrol. I believe the petrol pump did not pump petrol it pumped air.<br> <br> I took the slip but I am not happy I want my R50 back or something
