Absolute shockingly bad service with empty promises and hung up calls

On 23 November 2017 I bought a Hisense fridge from Makro online. The purchase was allocated to the Silver Lakes store. Since the 23rd I have regularly been checking the status of my order online, on Tuesday 28 November 2017 I phoned Makro Silverlakes to follow up on the status of delivery as it had been updated to delivery status online. Each time I was put through to the delivery department my call was hung up/dropped. The same happened the following day when I called. On Thursday 30 November a Makro employee phoned me and informed me that delivery would happen at 10:00 AM the same day. I accordingly made arrangements to receive the order but no delivery was made. At 17:00 I phoned the store again and after being hung up 3 times I was finally informed that delivery could not be confirmed!! How is this possible that you inform a client of a delivery time, not deliver on said time and upon questioning of where the delivery is and when it will be deliver not being able to answer the client? This is unacceptable .
