Missed treated and failed services

So disappointed in Checkers Platinum Square Rustenburg and the way they handled my orders on the 24th of March I placed two orders to be delivered on the 25th of March between 16:00 and 17:00. At 16:30 I saw my orders was not even started and the estimate delivery time now moved to 18:00. I phoned the store to enquire regarding this as I am leaving work at 17:00 and for that is the reason I placed my orders as I did so that I don't need to go to the stores after work as I have a injured child that needs to get to the doctor. I was then told that I can collect my order but I won't be refunded my delivery nor the driver tips that I have paid. I then said that this was not right for paying for a service I did not receive the manager said she will get back to me. So i waited before leaving word 17:15 she called back and said I should come and fetch my order which she then confirmed that I will be refunded back into my account for the delivery and tips. I was not happy when I got to the store the drivers was sitting in the parking lot was even more unhappy. Got inside and it was not that busy at the sixty sixty department. I was then told that I had to still wait for the drivers to scan out the orders before I can leave. I then asked to speak to the manager which I was told the lady I was speaking to was the manager. She then said she can call her boss to come who even never came. I was not happy at how rude she was to me and that I had to wait another 30mins before I could get my orders and leave. I was then refunded my delivery cost back on the app with a notice that said I have 7days to use it. Now I am being forced to use a services which failed me so I don't loose my money and never got refunded for the driver tips after I had to go and collect my own orders and was treated badly for their service that failed. This is day light *******!!!!
