Undelivered online order

I ordered food online for delivery from Debonanairs Wonderpark. I paid for the food +-R191 it was on the 08/10/2020 around 19h50. The app gave me a map showing the progress of the driver coming to deliver. We waited at the gate by the time the app said the driver has arrived, no one showed up as we were waiting. We even stood up for more than an hour thinking he might have been delayed.... still to no avail. I called the store only to find it's already closed. I responded to the app complaining about non-delivery... no one called me back. The following day I called Debonairs customer care to complain, they told me the store will call me. No one called. I called again the other day they told me the store manager will call, manager called and said to me I should order again they will give me discount, I said I cannot... I should either get a refund or get my full order, it's not my fault I waited, and the store never made follow-up even after I provided my number on the delivery complaint. He claimed they could not get hold of me, but they have my 2 numbers and email. No SMS no email even if you claim not to be able to reach me on call. Then he said he will speak to his manager and come back to me, he never came back to me again. A day before yesterday i called customer service, they also said the store will call me, Im still waiting. Can i please hàve a way forward on this as I paid for the food I did not get.
