Engen garage Vosloorus sebenza is full of ******

I went to Engen garage in Vosloorus near sebenza on Tuesday the 12 April 2022, My car was empty and I poured R400, When I had to pay I was told that the EFT machine is not working I had to pay cash and I realized when I had left that they ****** me and probably poured R200 petrol instead of R400, that petrol only lasted me 2 trips, to and from work when it normally lasts me a week. I’m very furious that I was ****** daylight by people I trusted.
