Poor use of KFC app

I placed an order to do curbside collection at Beacon Bay using the app. Firstly the app does not work well I needed to re log in because it did not allow me to change my name. Then I placed the order, paid the amount, and arrived at Beacon Bay only to find it closed. No message, nothing. I sent a message on Facebook to the KFC page with all my details and still have not heard anything. The fact that KFC took my money with a store being closed is unacceptable. And then not to follow up 3 days later is very poor service.
