Extremely poor customer service

I placed an order at KFC in Ravenswood. The app kept flashing that irritating cartoon character, saying, "Sealing the deal". That did not go away as it normally does. Just before 19:00, I decided to cancel the order. I was not even aware that the driver has at the gate 20 minutes after placing the order and they would normally call when you don't respond to their messages on the app. Not this time though, no call, nothing. I only realized that the driver was here after I had canceled.

Now they offered me a 50% refund because I should have been here to receive the order, which I was. Had a WhatsApp chat with their support team, which was not helpful at all. They connected me to an agent by the name of Aphiwe, who seemed helpful at first, asking me to provide my details, only to turn around and be very unhelpful.

The 087 number they say you must call, does not even work, go figure. This is as poor customer service as I have ever come across. They are running a **** and fleecing customer due to their poor maintained app and blaming me for the unsuccessful delivery attempt. I want a manager to call me back ASAP, if not you leave me with little choice but to continue exposing your poor customer care and general conduct. You have my details.
