BP sells contaminated Petrol

After filling up my vehicle on 15 June 2022 @ 16:45 @ BP O'Reilly Merry street, Benoni, my car suddenly would not start the following day at a shopping centre. After I had to tow in the vehicle and many parts later a mechanic suggested that he drain the fuel tank and fill with new TOTAL petrol. Problem solved! At the current price of fuel it is shocking that a BP garage can sell contaminated petrol that almost cost me my vehicle. I have reached out to them but no reply...
