Sasol ripped me off R150.00

On Friday afternoon I drove into sasol garage in Silverton to fill in petrol. When I got there I asked a refill of R150.00. But what surprised me is that when I got there, there was already R150 refilled from that pump. I gave the petrol attended the keys then he opened and claimed to refill. But my gauge did not move. I complained that the gauge on my car did not move then they told me that perhaps it's not working. I drove to shoprite silverton, then back to Mamelodi West. The total kms that I drove from Silverton to Mamelodi was 10 kms then the petrol light was on that's when I realised that the petrol attended did not refill my car. I refilled again with another R150.00 in Engen garage in Mamelodi west then the gauge rose to just below half tank. I called Sasol garage in Silverton to tell them my problem but Emmanuel told me that he would investigate. He called me the next morning on 25 July 2020 telling me that what I told him is highly impossible. He told me the way my I don't know how my car's gauge operates. That was really insulting to me the way he told me. It was as if I'm clueless about my car just because I'm a "WOMAN"
