Extremely bad customer service

On Sunday 30 August 2020 I purchased a refrigerator from Makro and prior to the payment I asked the sales guy if they do deliveries and he included the delivery fee. I asked when the delivery will be made and he indicated that it will be during the course of the week. Thursday, 3 September 2020 at around 15:00 I then initiated the call to the company and enquired about my delivery. First the guy tell me that he was told that I am looking for him, I did not dwell into it as I just thought that they deal with quite a lot of customers and he could have been busy at the time. He then tells me that the delivery will be made on Friday or Saturday which I told him that Saturday is not feasible as there will not be anyone to receive the delivery. Today (Friday, 04 September 2020) I called the sales guy directly at around 13:30 and he assured me that my delivery is on the way and the guys will call me when they are close by as they left in the morning with other deliveries. At around 15:30 I received a call from the delivery office asking about the location as the item is still with them and will schedule delivery for next week Tuesday. After a lengthy discussion he said he'd revert back to me and he did now with a solution that they'll squeeze me in with tomorrow's deliveries that are heading to marble hall. Like why am I being squeezed in if: 1. I was informed that the delivery will be made during the course of the week. 2. I made the effort to find out the status of my delivery 3. I was falsely advised that my delivery is underway for today.

I told the guy to revert back to the sales agent that I want my money back as they failed to manage expectations. The sales guy said he could not hear me on the phone and he was dealing with a customer. Am I not a customer now that his sale was concluded? His manager then reverts back to me to tell me a different story that does not tie back to the two gentlemen's stories who are colleagues of hers (another red flag). When I asked he was about the purchase date of the deliveries that the made today, only then am I being told about a backlog. Like why was it not said upfront prior to the sale being concluded. Now am being told that to get my money back will take up until next week Tuesday. Like what level of mediocrity is this?
