ENGEN SELCOURT SERVICE STATION (SPRINGS)

It is unfortunate that I have to resort to doing this but the manager at Engen Selcourt service station (springs) has been very unhelpful. Situation: I filled my car with 95 unleaded on 2 May 2025 (unfortunately i did not take a slip as I used cash on this particular day) that caused my car to go in "limp mode" on 9 May 2025. I took my car to cassey auto springs to find out what the issue was with my vehicle. The report stated that it was contaminated fuel that caused the issue and because of this the warranty would not cover the repair. I had to pay R4718.04 to get the tank removed and cleaned. (Proof has been supp**** to the manager). I was then asked by the manager that I should bring the fuel sample the ford garage gave me so they can do testing to see if it was engen's fuel. I dropped off the sample 24 May 2025. Which he wants to charge me for???? If you want to test the fuel you can test it but you will not hold me liable for that cost. I have also repeatedly asked that he send me the video of the fuel being put into my car and logs stating what fuel was put in. But this has not happened yet. Our last communication was on Monday 26 May and he as not responded or tried to sort out the issue in timely matter. Can Engen please advise on the way forward so this issue can be resolved.
