Poor service

I'm so annoyed with the service we received at Hi-Fi Corporation (Liberty Promenade in Mitchell's Plain Cape Town). We purchase a KIC fridge in August month-end and after a month using the fridge it gave us problems. When we contacted the store they informed us that the KIC technicians will contact us to come and check the fridge which they did after a week and a half. The KIC technicians informed us that the fridge needs to be replaced and that they will inform the store which they did on the same day (I need to point out that this was 3 weeks ago). After not hearing anything from the store for a week we called the store to find out what's happening with the fridge and the lady who assisted us informed us that we'll have to come and fetch the fridge ourselves as there's no proof that we paid delivery (which we did). We made an arrangement to bring our own transport and when we contacted the store last week Friday (20/09/2019) we were told the KIC fridge is out of stock and that they will inform us when we can come and fetch it. Today (25/09/2019) we came to the store to ask for our money back and we are told by the manager that the fridge is in stock and that they will deliver the fridge as we initially paid for delivery. Had we not come to the store to ask for our money these people wouldn't have called us nor deliver the fridge. This is possibly the worst service ever and the staff at this store is *********** and rude. We will never make any purchases to Hi-Fi Corporation and would not recommend it to anyone. They suck!!
