takealots service is becoming a horrible

On the 1st of October i purchased a Presonus v2 single channel tube pre amp from take alot, i was told that it would be delivered on the 8th of October. On the 7th (a day before it was due for delivery) my order was cancelled by takealot and the reason I was given was that the item is out of stock.

Why would they advertise a product they dont not actually have in stock? this is false advertising
