Nightmare Order cancellation.

On 28 Novemeber I ordered a Bosch hub for COD. It was going to be a gift but the person already purchased one himself. Monday the 2nd December I looked on my takealot app and saw the order has not yet been shipped. This apparently makes it easier to cancel a order and so I did over email. I then received an email that my order has been cancelled but because of stock ... not the order I wanted to cancel so I now sit with minus 3 Christmas gifts I wanted and 1 I do NOT WANT. Lucky for me I can decline the delivery but this is not on really how unprofessional. I have never had any problems before, why now before xmas???
