Order Processed and Item Paid for but NO Delivery and NO Help

I ordered a fridge online through HiFi Corporation's website on 10 February 2019. The money came off my account, I received an order confirmation and it was stated that delivery would take between 2 and 6 days. When I had had no further communications about the delivery date after a week, I clicked on the tracking link in my order confirmation email only to see that the process hadn't gone any further than "order processed". I called HiFi Corporation and was told that nothing had happened with my order and that the agent would raise a complaint for me and escalate the matter and that someone would contact myself or my partner in 24 hours. That was on Friday. Today is Tuesday and as yet, still no word from anyone at HiFi Corporation besides an automated confirmation that my complaint had been raised. I called HiFi Corporation again today (Tuesday 19 February) and was told by the customer service agent that he can see the problem is with the warehouse, but when I ask if he can contact the warehouse or give me a number that I can chase, he says no, that he now has to escalate the matter AGAIN and follow up with his head office. How is it possible that the order has been placed, the money has been taken, but no one seems to know why the fridge hasn't been delivered and that no one is able to contact the warehouse directly? I am utterly disappointed in the service I have received from HiFi Corporation thus far and sadly, I feel that the only option left is making a public complaint in the hope that someone will pay attention and that the fridge which I have paid for will be delivered.
