Horrible customer service and *****

I poured petrol twice at Sasol Boksburg, first poured 95 unleaded on my mini cooper S and I was poured air but when I realized it was too late because I was in a hurry, I went again on the 31st of October 2021 with a hyndia i20 and I was poured again but this time I caught it quickly and I reported it to the supervisor on shift and he said he'll pass it on to the manager, I waited a week and still no response and I asked for feedback and I was told the manager was notified and I was given his contact details. I went on to contact Mr Mtshali and he read my messages and didn't respond. This is horrible customer service and its unfair that they keep pouring air instead of petrol into people's car.
