Complaint about contaminated fuel

On the 3 November 2020 I went to BP in Richards Bay. And that evening after work my bike broke down. After doing a few checks I found that the fuel was contaminated. Took the fuel sample back to the fuel station to make them aware of the problem and asked for a feed back on this problem. After waiting for more then 3 weeks of no response I went there and made a query about this situation. They gave me back "my fuel sample" and found that it wasn't in the same container that I gave them including the fuel was a different colour. After not agreeing with the fuel in the container they carried out a fuel sample test, as they were doing the test they tried to convince me that the fuel sample I have wasn't filled with water but it changed colour to the same as the sample they showed which had water in fuel. So when I said it was showing water in fuel they told me that my story doesn't line up. So as per this experience I will not advise anyone to fill fuel at BP Richards Bay in bullion boulevard.
