Engen garage

Hi I am really disappointed with the engen garage in hartbee****rt arts & crafts crossing,all the way from Johannesburg to sun city going the for a birthday party,we pass on this engen garage to to put a fuel then one of the workers poured in petrol instead of diesel, we got stuck on the road for 2hr we had to go back to the garage to drain the petrol and put in diesel all in all we spend our day at the garage instead of Sun city ,it was 10:15 when we put fuel in the morning and we left the at 4:00pm after fixing our car we need them to make it up to us for that day Mr R . Du toit please make means for us to see sun city again.and stop hiring new stuff every time train the ones you have .thank you
