Misleading and misrepresentation of goods

I was misled by the salesman to make an online purchase under the impression that my goods will be delivered assembled by the store. I asked the salesman to confirm that the bathroom cabinet and its matching mirror cabinet will be delivered already assembled off which he confirmed. I asked him to describe how it comes and he said the same way it has been displayed . He then said he has no stock available in store and that I should order online and pay for delivery. I made the order and paid. While tracking the order I then realised that the goods were actually available in store and ready to be shipped. I went to the store and was told the box is available but the issue is with delivery, they asked me to take the box and when I asked why it wasn’t assembled, they said the salesman **** to me about assembly. I asked them to assemble it since I paid for delivery and I’ll collect it. The department manager refused and said I should pay for assembly. I asked for resolution since the issue was created by them and they opted for cancellation. I proceeded with cancellation and to my surprise the head of department in the tills by the name of Palesa Moshweu informed me that I will get my refund after 10 days. I told her I wanted it in cash and cannot wait any longer as they have provided no resolution to my complaint. She refused and told me about the online refund policy. At any given time these managers could have resolved the matter without cancellation or refund immediately considering that they were at fault but they failed. They have violated the consumer act and continued to make the refund unfavourable. The standard of management in Leroy has dropped significantly with unqualified managers who fail to provide resolution to simple miscommunication.They failed to take accountability for their action. They have wasted my time and effort . I have never experienced such service as a long standing customer and it shocks me to experience such behaviour with the people employed to provide service.
