Very Bad Attitude

Went to capital Park KFC and used drive through. I placed my order,paid and proceeded to the next window for collection and when I got there my appetite was messed up by a rude and *********** KFC staff when I told her my order was wrong she said I'm the one who didn't say what I want, :-o. And bare in mind the same thing happened for two consecutive days. She even remembered I was there the previous day and with a bad attitude as well she rep**** to me saying "even yesterday you did the same thing" . Well say for instance I was wrong of which I wasn't, she should not be giving customers a bad attitude unless otherwise I don't know what is a good customer service. Ronewa(the lady who assisted me) must undergo a serious customer service training.
