Samsung Electronics fridge replacement

In March 2020 I purchased a Samsung Fridge from Dion Wired in Hyde Park. The ice maker never worked and Samsung sent out technicians to effect repairs. On the third occasion Samsung through their agents All Electronics informed me that the ice maker could not be repaired and that the door would need to be replaced. I have email correspondence from the following dates: March 3 2020, March 4 2020, March 28 2020, May 13 2020, September 30 2020, November 24 2020, December 1 2020, December 4 2020, and December 10 2020. In the last mail I was informed that an exchange was approved and that I must contact Samsung directly to arrange the exchange. I have subsequent to that had literally dozens of phone calls - each time I am told that the case is being escalated, at that I will be called back - I have never received a call from Samsung. I am now being told that I should go to a different store (as dion Wired Hyde Park no longer exists) and manage some sort of exchange myself - as Samsung does not have that exact unit in stock. This might be the worst experience I have ever had with any company ever. All I want is the broken fridge removed and a replacement unit delivered that works - but that seems completely beyond the company.
