Pizza not delivered

I placed an online order and paid online on the 26Oct19 at 17h02pm for Debonnaires Protea Glen and I kept calling to check how far is my order and was told its on its way and other person said they are too busy as it is month end. After 2 hours waiting in vain still no delivery I called and was told its on its way and waited for another hour still no Pizza and eventually I decided to get something with myself and wife and we went to sleep and minutes later I got a call from a guy by the name of Michael asking if we got the pizza and said no and went outside to check if someone is outside and he hanged up. The following we decided to go personally to the shop and ask for a refund and Manager by the name of Tumi promised to do a refund and asked for my email address to send me what he will process and I should get my refund within 4hours and to date I have not received my refund. Today I phoned the shop and spoke with Maria who tried assisting and she left the shop and handed over this matter to another person by the name of Rhulani who just called and call got cut off and I don't have energy and money to keep calling Debonnaires as I have called them more than enough on the 26th and again today . I am frustrated of how this is handled. I even phoned the customer care to assist in this matter. I am very dissapointed of their services. And last order I did they brought a cold pizza and I just took it and warm it myself.
