Delayed delivery-twice!!!

Having placed an order for liquor on 2 June and being told that delivery will take place on 8 June; then two further emails stating delivery has been delayed to 15 June then 17 June. Trying to contact takealot is almost impossible- I filled in the form online asking that the one item that is delaying the order is to be cancelled but to date I’ve had no response. Now with another alcohol ban looming what chance do I have to have my delivery on time ??? Why can Checkers Liquor deliver on the same day but my order through takealot more than two weeks??? As I have used takealot often I didn’t hesitate to use them again. Not so sure I’ll do it again!!!
