Incorrect Delivery Information

Last night I bought several items from Takealot. Initially there were more than two items in my basket. However due to the indication that the items would take longer since they were not in stock I made separate orders. Order (***) has two items which were indicated to be in stock. When I checked them in the delivery date was 27 June. I was happy about this since one item is a birthday gift and I need it for Saturday. After I had paid for the items the date is now Monday,30 June. This is not the first time I have encountered this with Takealot. It is not right at all. Once you indicate a delivery date stick with it. I am really upset. I have so far found Takealot to be professional and decent however misleading information erodes trust.
