Cancelled Christmas Order without warning

Ordered Christmas gifts for my kids well in advance of the Christmas delivery cut-off and only 1 out of 7 items arrived. Queried it, and after an investigation (additional two days), received feedback that my order would be delivered on the 20 Dec. On the day that I am expecting delivery, I suddenly receive emails stating that my Takealot account was credited with the amount and the order was cancelled!!!! I now have to rush to the stores to pick up last minute Christmas gifts and hope that I can find the items that I’m looking for at the same prices I paid on Takealot. I also have to pay additional cash for these items as I can only use the refund on takealot which means that I’m forced to use their services again.
