Total Newtown Petrol Station

I recently poured petrol at Total Newtown Johannesburg and to my surprise my tank never went up. I never thought that the stories were true that petrol attendants can actually fill your car with air but it did happen to me. I suggest that no one go to Total Newtown because of what happened to me and i wouln't want that to happen to anyone. What if i got somewhere and the worst could have happened to me? I am highly disappointed.
