Bad attitude

On the 16/02/2016 went with my boyfriend in vangate McDonald drive through,he placed an order then he asked me what do I want...I answered him then decided to change my drink to a McFizz the Sisonke was angry she was shouting at us then she said DRIVE THROUGH,as she was angry.i reported this to the manger Xolani and he said he will deal with her but still she was shouting Xolani. I asked her to come around because she treated us so badly wanted to tell her she did not came she said she does not want to.....really had a bad service and I wish there will be something that will be done with Sisonke's attitude,even the staff they were asking why you angry...she was banging stuff as she is placing orders
