Poor customer service and bad behavior and lack of integrity and respect

We went to Engen Clayville conv centre 72 Olifantsfontein road and my husband,the lady with the name of Mazella Rikhotso(a petrol attended's) was assist us to put petrol. We gave her our clicks club card to swipe for points, she take it and gave to a guy who was driving Tazz and she abandoned us without saying anything. I went to her and tell her that we are still waiting for our card that she gave to that guy and the slip (proof of payment). She was very rude to me and she told me that she doesn't have the card what can she do she insulated us and shouted at us, instead of apologising, she said she made a mistake like any human being and there is nothing she can do. She shouted at us until one of the customers rebuke her and tell her that she is very rude and she will chase clients away and her bad attitude and behaviour will ruin her life,she said she doesn't care. One of her colleagues tried to call her into order and she ignored him. She leaved us to assist other customers until her colleague calls the manager over the phone because he was already left. He explained to the manager what happened and the manager said we have to come back tomorrow as he is not around. Now my clicks club card is gone with a stranger and she didn't care about giving us a till slip.
