PATHETIC DISGUSTING SERVICE!!!!!

I am so disgusted and livid with the terrible SERVICE that i have recieved at this macDonald at Umlazi kwaMnyandu Mall.The RUDE, SELF centered cashiers who were Thokoza and Thandiwe were extremely rude when i placed my orders via intercom as i was In my car and then decided to add another order on Top of what i have ordered , they told me that they could not assist me becuase i have placed orders and they told me harshly that they cannot place another order for me and Demanded me to go join traffic que again and place an order. They then kept calling each other mocking me In front of my family that i should go and join the que with a terrible ATTITUDE....i waited about 10 minutes ans still they refused to place another order...i demand immediate response ffrom manager and from those *********** cashiers with No manners and No customer SERVICE....
