Debonairs takes peoples money without providing services

I ordered pizza from Debonairs Lambton on Friday 21st February 2020 via their online channel. Payment was made. After 40 minutes I was called by the store manager Samantha Jansen stating that they were unable to make my order as they were load shedding. I requested a refund to which the manager told me she would contact me once speaking to the owner regarding providing me with a cash refund as payment had already been made. The entire day had passed. Around 4 pm I made my way to the store to be treated extremely rudely by Samantha stating that they called me and my phone was off, her sarcasm and rudeness really was not appreciated. I went on to call customer care and until now I have not received my money back. Customer services had also reported that the store manager had marked the query resolved. How is this possible when I haven't received my money yet? I have not received any communication from Debonairs. I will not be purchasing from Debonairs again as it seems to me they take peoples money without providing the services!
