Poor Service -refusal to split delivery and slow delivery

I have been supporting Takealot for years, doing countless purchases. On order ***6, two boxes of wines were delaying the delivery of the full order. Takealot had received the other items. As the other items were urgent, I requested them to split the delivery, which according to the website they can do. They refused. I had to cancel the order for the 2 boxes of wines to enable delivery of the other items to be quick, but I still have to wait for delivery on 15 June. Poor service, disappointed, especially on not splitting delivery (all items are >R450)
