Engen orkney near golf course

So the other day I needed fuel so I stopped at the engen garage near the golf course in orkney.. I needed something to drink so whilst that was being done I thought I could quickly go and buy me something.. So the guy told me I could pay inside.. So I did.. Came out and drove.. Not very far from there I noticed that the petrol gauge is not lifting.. So I wanted to go back but I had an appointment half hour from the time it was then so I went to klerksdorp.. When I was done I went back to that garage and there was nothing done about the matter.. So it's money lost for me.. So whoever uses that garage best make sure that your fuel is added to your cars.. This is so disgusting seriously.. With how many people does that guy do this.. I will never even support that garage again..
