Pay and don't receive.

I purchased a washing machine on 25th November 2022 along with a deep freezer. Upon purchase no one informed me about any availability or stock quantity, I was told delivery would take place the following week. The week after purchase I received a call from the store informing me there was no stock of the washing machine, can they supply me with the demo model? I rep**** saying no as I paid for new. Two weeks passed and I received a call from another lady enquiring when will I collect my freezer... I then informed her I am waiting for my washing machine and they should deliver. No reply after that. Three days passed and I still never received or heard anything so I called and requested the store manager number. Where I sent my sales order proof of purchase and requested a follow up. She arranged for my freezer to be delivered and said she will follow up on my washing machine. Another week passed and I sent another message asking for feedback, she informed me the truck was off loading she will Inform me soon. Later that day I was told nothing came. I told her I am not happy and it's unacceptable for them to expect me to have already paid for something and have no use of it after an entire month. Sge apologized and said she will see what she can do. Well...it's the new month and year and I am still waiting.
