Takealot failed to deliver my order and now doesn't want to give me my money back.

I ordered a birthday gift for my friend at Takealot order no #*** and it was due to be delivered on 8 December 2022. Someone from the courier company called me on 7 December 2022 and asked for direction to the delivery address and I gave him. He never came yet on a portal it was written delivered. I wrote to them asking why my portal said they have delivered my order whereas they didn't. They checked their system and found that the order is still in the courier company and someone from a courier company called me telling me that they will deliver my order on the following week. I told them that I don't need the order anymore. I want my money back. They said they will give me the refund. After some time I noticed that I am not getting my refund and I then contacted them again. They started afresh telling me that they delivered my order on the 7th and I had to explain again that it wasn't delivered and they said they will investigate. They came back saying they found out that my order was not delivered and said they will deliver it and I told them that I don't want the order anymore I want my money back and they said ok they will give me my credit back. Time went by. Nothing! Now they are saying they delivered it on the 20th and at my work there is no one since 9 December 2022. All I want is my credit back and they keep on tossing me like a coin and I have to explain the same thing over and over again to different people. What as pathetic service with Takealot. I trusted this company and I buy from it a lot but I am really disappointed of the service I receive from them.
