Delivery fee **** from Takealot.

Two items of an order were cancelled by Takealot from an order that I made on the 30th September. On the day of delivery Takelot said that two items were not available and cancelled them. Then I received notification that they were sending the product to me today, but were charging a delivery fee of R70.. My original order was for an amount of R683. The aluminium trolley plus the Cokes were cancelled by Takealot - and not by me. When I queried this they said that I placed a new order for the product and the new order is under R500 so I have to pay the fee of R70. But I never placed a new order.
