Delivery date not met

I ordered a video game which had a delivery date of the 23rd December. When querying why the delivery had not taken place I was told that I had not paid for the item which had been done via immediate EFT option on the day the order was placed. Proof of this was sent through to takealot via EFT which they have acknowledged receipt of. However due to this they are now quoting a delivery date of the 31 December which is over a week after the original delivery date. This product was a Christmas present and I deliberately took the time to confirm that it would be delivered in time for this. Had I been told that delivery was not until the 31st I would of bought the product else where!
