Makro online poor service, No refund 22 days after cancellation

I ordered a Hisense Fridge (R15999) on the 24th of May 2023-Makro Online. On the 28th of May 2023 I cancelled the order, it had not been delivered yet. I kept calling Makro online to check on the progress of my refund they telephone operators kept reassuring me it was cancelled and I will be refunded in 7 days (ref number for call ***). On the 9th June that same fridge got delivered. I sent it back with the courier WumDrop the very same second they delivered it. I called Makro online again probably the 20th time and was then told my order had initially not been cancelled, they can’t track the fridge, the refund should be processed by Makro Woodmead. I then called Makro Woodmead spoke to the manager who said they will call me back. I type this review with so much anger because today the 19th of June, 22 days after I cancelled my order, more than 20 phone calls made, emails not responded to, I am still waiting for my refund. I called Makro online again today and was told Makro Woodmead has not processed my cancellation or my order. How is that even my business when I placed the order online and not at Woodmead. The fridge is with Makro, my R16000 is also with Makro. At this point I don’t even know if I will get my money back.
