Online order no delivery to this day

I bought a Hisense Fridge online at Makro that was on special, on the 26th of January and the expected delivery date was the 28th of January. Till this day I haven't received it. I first got a message from them on Tuesday the 28th saying there has been a delay but after that there was no communication from them. I phoned on Saturday the 1st of February I was told the fridge is with the courier service, the manager will phone the courier and revert back to me within 24 hours. But that didn't happen, I phoned again on Monday the 3rd I got the different story. They told me they dont have the stock at warehouse and dont know when are they going to get the stock. Its the same response I got yesterday the 6th. When I asked for a refund they said they will check if there's a store that has it first before they can refund me and their refund takes 48 hours.

I am not happy with the service am tired of calling them, the fact that I'm the one who has to do the follow ups. There's no communication from them, its been 2 weeks no product and no fridge. For such a big company this is unacceptable, if there's anyone who can assist please do.
