Horrific treatment and refusal to give me a cash slip

Put in R200 petrol at Engen Olivedale Corner this morning Asked for a cash slip. No sorry you cant get it says Victor as you did not ask me for it before i put the petrol in - ? I did not ask - or you didn't as me - works both ways. There is NO sign stating you have to say you want a Cash Slip before they dispense the petrol either. Enter Sam - what a darn ******! No respect for women. He told me JUST where to F OFF. Refused to give me the owners details - told me i can do what i like and started serving the customers int he store just ignoring me. I want a meeting with the Indian gentleman who i know owns the store and me him and Sam need to sit down and have major words. Sam is not an asset to your organization. By law i am entitled to a Cash Slip.
