Late delivery

I ordered a few items, on the website next to the items it says: 5 to 6 days delivery. I thought by myself, well that is not too bad, I will place my order. But after I made the payment, I received an email from Takealot telling me that my order will be shipped 14 days from now. Why now all of a sudden it's 14 days and not the promised 5 to 6 days delivery? I am not happy at all.
