Pathetic Service from Store Manageress

The store needs to take a look at the Manageress - Ayanda. She is completely useless at her job. Has no care for Customer Service- I doubt she even knows the meaning of the words. I called the store yesterday after ordering on the KFC app. The money was taken off my account and no order was processed through the app- a glitch on the App side. I had called the store first around 6h20pm, she told me that she would call the driver and get back to me. 15 minutes passed no call back. I called her again, she told me to give her 5 minutes - she was going to escalate my issue with the call center and call me back. 20 minutes had passed and no call from her. I called her for the 3rd time - she told me to hold on, she will look for the piece of paper she wrote the customer care agent's details on-to give me. I held on for 9 minutes and 46 seconds. She then cut the call. I go into the store to buy my food cash, wait for my order, then call for the Manager. She didn't expect me to come into the store. Only when I called for her - did she get onto the line with the Call Center. Something she told me she did about 30 minutes ago(at that time). She gave me such an attitude and was absolutely rude . How in the world does a person like that get employed in a Manageress position. When you have workers there employed over 10 years that can't climb up the ladder . 90% of the workers there took it as a joke, KFC Bayview- kindly tell us how you employ people like this ???
