Poor Service At KFC Rivonia

Experienced bad service from a man who identified himself as Rowana from KFC Rivonia, I went to the branch to order food from the drive through, asked for a Colonel Burger meal with a cup fanta, after a had paid and drove to the collections window i discovered that the lady had made a mistake by noting my order as a burger and a drink only with no chips. I asked for my chips and the ladies that were helping me called the manager with the above name who faild to identify himself to me and made me wait for almost 10 minutes before resolving my query, he refused to give me my change of which he eventually did after i saw that i was not prepared to leave without it. This was the poorest service i have ever experienced from that branch and it sad because i buy food at that branch on a weekly basis.
