No Stock, but still able to buy.

I have bought a toy for my puppy on Takealot and only on the day of delivery they e-mail me saying that they are out of stock and can't find it at any supplier. I have waited more than a week for the delivery to come and then there is not stock? I just went back on Takealot and added the item to my shopping cart again, how is that possible? There is no indication of the item being out of stock and I am able to add it to my cart. The system should not even have the add to cart button available when there is no stock for the item and be replaced with 'out of stock' text.

I was refunded but it does not help if I am able to buy the item again. I have gone through the whole process of buying the exact same item again on Takealot and my credit that Takealot gave me was used for it and my order was approved by the Takealot system.

So Takealot how do we go about fixing the issues I have with the out of stock item that I am able to buy more than once?

I payed for delivery again so a refund will have to be done by Takealot again unless you have this item in stock.
