Useless service

I ordered a Defy refrigerator on the 4th of January 2019. The delivery time was estimated to be between 3 to 5 days. I thought this was a decent time as I have recently moved from Jhb to Cape Town and moving into my new place with my two year old. A week later I contacted the call center to find out what the delay was and they told me they had no stock. How do you sell something without having stock?? I was informed that they will receive stock by the end of the month and I was not happy with this because I am a single mom with a two year old without a refrigerator and I needed one urgently. I then decided to cancel my order and was informed that it will take 7 to 14 days before I will receive my refund. I was ok with this and asked them to go ahead and cancel. 3 days later my cancellation was not even captured on any system. I was furious because my time is being wasted and the call center people aren't doing their job. A day later I received notification from the courier company that delivery will be done that particular week. Nobody informed me of this and I was thinking my order was cancelled. I then had to call the useless call center again to cancel my order cancellation. My refrigerator then arrived and upon opening it it was damaged inside. There are holes in the plastic inside. I immediately took photos and lodged a support ticket online and also called the call center the following morning. I was promised that they would organise collection. Well it's been a week and I have had many promises but nothing happened so far. I just want a new refrigerator and if this is not possible I want the faulty one to be collected and my money refunded. Can someone just get back to me!!!!!????????
