Rude Caltex Employee

I went to Caltex garage in BramFischer road Randburg to buy myself a pie and chocolate, I was assisted by a teller by the name of Fezeka (if not mistaken) and i was paying with my Capitec card.she swiped the pie only (i did not realize) and as i was about to leave she tells me she not include the chocolate on the transaction in a very rude manner, She then swiped my card again for the chocolate without asking me for a go ahead and when i asked her she said just I said i need to pay the chocolate. I asked her why did she only pay the pie she told me she did not see the chocolate and she doesn't understand why i am shouting( with an attitude and even clicked her tongue on me).She did not even apologize that she made a mistake.She was very rude like i am the one who made a mistake even has guts to click her tongue at me its not acceptable and did not care of my bank charges. I could not ask for her manager or supervisor as i was rushing to work.
