Builders Zambezi - Online Dehumidifier Refund

I purchased a dehumidifier which was marked in-stock at Builders Zambezi (PTA) and was scheduled for delivery on 10 June 2020. It wasn't until I called to inquire about the delivery that I was told that the item is actually out of stock and the only item that was available was the demo. When I asked for my money back as takealot.com was running a similar special for the dehumidifier, I was told that Builders had already placed the order with the supplier.

On 12 June the branch returned to tell me the supplier is no-longer making the model and that they would get back to me regarding either a substitute or refund. I had to call back on 15 June 2020 in order to get the order to be cancelled and get a refund. The item is still showing as available on the website (now at full price), I just wonder if they are planning to sell the demo now at full price after refusing to sell it to me at a discount as the manufacturer said they are no-longer producing this item.

Please assist and get me my refund asap, I ordered this item because it was an emergency, and I think it is unfair that Builders is moving at a snail's pace to get my refund. I will never buy anything from you guys again, there is a lack of professionalism and care on your side, it feels like you are doing us a favor when you are supposed to provide good service.
