Black Friday went wrong - May we get our money back

My partner bought a fridge and a microwave at Hi-Fi Corporation on the 27 November 2020 (Order number: ***). On the 4th of December he received a call that the courier was outside. Since we were at work, we requested someone to collect on our behalf. The order was delivered by Tiyani on the 04 December, he informed us that he was only given the microwave to deliver. The delivery documents are for the fridge, yet the item that was delivered was the microwave. We logged the call immediately and were given a ***. We then contacted the warehouse number that appeared on the documents and spoke to Isaiah Shai, who told us that the warehouse manager, Thwmba Macebele was busy to take our call but will contact us. According to them, both the fridge and microwave were taken from the warehouse, and they do not know what the 'guy' did with it. After informing him that as a customer that is not my problem, it is their responsibility as a warehouse to investigate, he told us that Temba will get back to us as soon as possible (no date specified). On Saturday, we received a message that *** was resolved. We followed up with an email to which Themba informed us that he will get back to us on Monday. On Monday, 08 December, Temba contacted my partner and informed him that the fridge will be delivered on Tuesday. On Tuesday nothing happened, both my partner and I called Temba, we could not reach him because he said he was busy. The person who answered the phone at the time even shouted at me, telling me that she is not a store manager or a consulted and leave the phone, until I dropped it. The on-line ordering system for the store is *******, they do not know how to handle orders nor the queries following. They do not care, even when the executive is copied in the email, there is no joy. We went to Hi-Fi corp in Fourways to report, unfortunately their system do not even work together. This is all a mess. All we want at this moment is our money back, they can even collet their fridge. This is the worst service anyone could ever experience. Incompetency and lack of customer services.
