Sales team not understanding and false stock advertised

I ordered a few items from Takealot last week, with the understanding it would be delivered on Friday. They moved it to today. The problem came with the 74%Off Sofia The First Eco Sport Bottle I ordered for R9. It wasn't in the box. I call the call center, and after checking they tell me the item was cancelled, without telling me about it, due to a problem with stock availability. I tried to explain it is unacceptable as it was advertised and I ordered it, so they should replace it with something else for that price. The lady I spoke to just again explained it is out of stock - sorry. Then she bluntly tells me to have a good day and puts the phone down without offering any kind of help of understanding. The item is still on sale on their website for that price...
