Non delivery of items purchased - part two

This is a follow-up on my previous review on Friday, 9 October 2020. Once again another week has passed. After receiving my request to cancel my order on Friday, 9 October, Matlatsi phoned and convinced me to give her a chance - that she would update my order to a mattress that was in stock and that it would be delivered early in the next week. After posting the review on The Mattress Warehouse on the same Friday, I received a call from the Customer Relations Manager herself, promising to call me back on Monday. She had spoken to the representative regarding a mattress which was available, and would call me on Monday to confirmed. Monday came and went, with no call from the company. On Tuesday I received a call from Jean once again. He also referred to having spoken to the representative and confirmed that he would rather provide me with the mattress that was exactly the same as the one that I had ordered, albeit under another name. He mentioned that he had to speak to his manager to determine when the bed would be delivered, but that he regarded my delivery as a priority because I had already waited so long. Apparently his manager did not agree with him, because I have still not received anything or heard from him or the Customer Relations Manager again. I can only imagine that the fulfillment of my order was passed down, but never followed up. After the prompt response to my first review, I had actually been looking forward to revising my rating and providing a positive review on my online shopping experience with The Mattress Warehouse, but sadly this is not the case. I am frankly at a loss as to what I should do next in order to get the items that I have purchased and paid for delivered to me. The refund on delivery charges which was requested on the prescribed form on 7 October 2020 has also not been done.
