Bad service and staff member swearing at me

I went to Shell Auto City in Newcastle KZN at Murchison street on the 14 June 25 at 8:00am. All I need was to pump my tyre. When I got there 3 staff members ( Tomas, Marsha and Sandile) were standing next to shop door. And Tomas started by saying "Just say the compressor is not working"... Sandile came and I asked if he can pump my tyre and he aggressively asked which one. While doing he was still talking to the other 2. And they continued saying we told you to say the compressor is not working. I then starred at the 2 , Sandile said he's done while I'm still concentrating on the other 2. He then said to them "She's not even saying thank you " that's when I asked if are they talking about me and said yes. I said I won't thank you for doing you job and he said to me f&%k that's when I also showed him a middle finger while driving off. I am a manager at a business close to that shell and I will make sure that non of my cars don't fill up there.
