Engen Blu Bird Midrand sucks

Very bad. Service at Blu Bird Midrand. I am a very angry customer! Attendant put petrol instead of diesel. His fault. Was busy chatting to his friend while assisting me. Manager comes stand behind the car. No apology. No explanation to me as a customer. Nothing. When I confront him he says he thought i was busy. With what exactly. Complete waste of my time. *********** staff.
