Unhelpful

I tried to cancel 4 items off my takealot order BEFORE it has shipped. A very helpful agent cancelled 2 of the items but not the 2nd two. So I emailed (on the same day) to cancel those 2 as well. The agent I have spoke to says the order is "In process" so I cannot cancel it. Even when I explained her colleague cancelled the other items for me just over an hour ago. So now I have to go through the inconvenience of having the items delivered, filing a return and then waiting to see if I can get my money back.
