your employee broke my car

Around 6am this morning i went to one of your petrol station to pour patrol. Your patrol attendent, after ignoring all my other request broke my petrol cap and still had the nerve to say it wasn't him. He then proceeded to ignore my frustration and told me i was blocking traffic. The young man in question is Jacob and this is according to his supervisor. I would like to have this issue resolved and done so quickly. The petrol station in question is in Country view Midrand.
