Delivery Date Changes Without Notification

I purchased items with a quoted delivery date of 22nd December 2017. This morning when I go on the site to track my orders I saw that the delivery dates where changed to:

Order # ********** 7 - 27 December 2017

Order # ********** 6 - 28 December 2017

This is extremely inconvenient as these are Christmas gifts and now the recipients will not get their gifts on Christmas.

Takealot did not send me any communication about the change in delivery dates. I would not have bought the items if the quoted delivery dates were after December 25th.
