False promises

I ordered a book (order number: ***) at the end of June/July. I was told it would take 30 days to deliver, about a month after that I still had not received the book. I was told that it had to be brought in from America and I could expect my delivery on the 20 November. This week I inquired again about when the book would arrive and was told that there was an error at the distribution centre and they need to re-order but there is no stock to re-order from. They very politely state 'we can refund you for the item and sorry for the inconvenience' - This does not solve the problem! What frustrates me is that they could never stick to what they said and that I have to keep following up with them to find out what is happening. I've used takealot before and have been very satisfied but this is ridiculous.
