Item not delivered, store refusing to cancel the order

I recently wrote complaining about a titanium entertainment unit that wasn't delivered and the store promising to do a follow up with me that they never even bothered to do. After reviewing them here, I received a call asking me if I have received my item and that was on the 29th of November 2019 and I told them that I didn't, they apologized and promised that the issue will be resolved. This item was actually ordered on the 17th of November and even today, I do not know if I am going to get my money back or what. On the 2nd of December, I called the store to cancel the order and I was told that the delivery vehicle is on it's way to deliver the item but it never arrived, I told them that if the item doesn't arrive before the end of the day, can they please cancel the order and refund me, I was promised that they will do as I have asked. I also sent an email on the 2nd after past 5 when the order didn't arrive as they promised asking them to cancel the order. I called on the 3rd to check if my order was cancelled and I was told that it wasn't cancelled, I asked them to cancel it and I was also promised that they will do a follow up with me. I haven't heard anything from them since the 3rd, I find this so unprofessional. I don't expect them to deliver anymore, all I want is my money. I don't what else they want me to do because i have been calling them ever since the 22nd of November enquiring about my order. The 2nd of December wasn't the first time I asked them to cancel the order, when I kept on calling them on November, I told them to cancel the order but it looks like they don't want to do either of the 2 things. I even have numerous emails that I sent to the online customer care department asking them to cancel an order but only got the automatic reply. One of the days when I called, I asked the person on the phone to pass the message to the person who was supposed to attend to those emails and the name of that person is Fatima to please ask her to cancel the order. I find this very unfair because I have spent more than R200 in the past few days trying to communicate with them which I won't get back and I have to keep calling like a fool being transferred from one person to another. Writing a bad review about this store is clearly not enough, if anyone can advise me on the legal route because I'm tired of the store nonsense, they clearly know nothing about customer service. The order number is ***
