I want my refund on my purchase

On the 13 Jan 2022 I purchased streetwise 5 on KFC app( ref Khaya***) and was informed that delivery was going to take place. 10 min later I get a call from KFC telling me that they can not deliver and that I must go to Ferndale KFC to collect. I then wanted refund as this is an inconvenience and no longer wanted the food. However KFC has still not refunded my money. I have log a query and called numerous times( ref CAS-831368-D9F5Z1) and been promised that money will be refunded into my account with in 4 working days. But nothing has happened as yet. I just want my money back so I can forget this whole ordeal and this about the principal that KFC was quick to take my money but now are giving me a runaround when it comes to my refund. Hopefully the directors or managers at KFC see and read this because I do not understand why they are not refunding my money. I will definitely not be recommending delivery service to anyone.
