Rude and unprofessional petrol attendant

Dear Astron, i visited your pertrol station Marlands branch this morning and received the most unprofessional service from your staff. I went there to pour diesel. The petrol attendant who was assisting me didnt ask me whether oil and water is fine. Ok i passed that, when it was time to pay he didnt ask me about the points card. I then asked him whether the garage no longer request card for points since he only swiped my payment card, he just simply walked away. I then asked the other two attendants who were busy with other customers to assist me. One of them came and i asked him whether they no longer ask for point cards, he said they do and assisted me. The attendant who walked away now came back after he saw his Colleague was assisting me. I asked him why he is giving me unprofessional service, he just shouted like i am bothering him and walked away again. We have been using this garage for years since it was caltex and we have never received such bad service. I personally choose to buy at this garage instead of other garages because of the good service we have always received. Your unprofessional staff gave me a slip that was not written his name on. My card was swiped at 8:12:45. His Colleague who came to assist me with a points slip gave me a slip that showed a name and the slip was printed at 8;15am the second slip was written P Tshibaloni. Astron, this particular staff who gave me unpoffessional service is really dragging your brand to the mud. we will avoid using your garage because of one staff member who disrespects customers. For the first time in history of many years, I have never been assisted by such a rude staff member.
