Worst Service Ever

I stopped at Engen 1 Stop Big Bird in Midrand to fill up fuel on the 18 December 2019 at just past 10am, i waited almost 15 minutes and no one assisted me, what pathetic service, or should i so no service. I even got out of my car to stand in front of the car for someone to acknowledge me, i just watched as every other car that pulled up after me was being helped. I went to the toilet and came back and still there was no one to help. I then just left. Worst service ever.
