Takealot Not Delivering

I ordered products worth over R5000 from Takealot. Order Number: ***. Some were for a birthday party I am attending on Sunday. 5 were gifts for people I am seeing at the birthday parties. I specifically chose 'in stock' products so that they arrive before Sunday. Today I get an email from Takealot informing me that there is a delay and the products will only arrive Tuesday, 2 days after the birthday party. My issues - (1) If I take the time to order 'in stock' products, I should have the reasonable expectation that the products will arrive at the time promised to me on checkout. (2) Things sometimes happen. I understand this, but I am not given an option on the website to cancel the order. I have to go ahead with it, and then book them for a return after they have been delivered. The products are not yet sent out, but I cannot cancel the order. This is ridiculous to say the least. There should be an option to cancel if the order has not been shipped. So, I have to wait until the goods are delivered, book them for a refund, fill a form, and send them back, when I could just simply cancel the order or an item on the order. (3) This also means that I now have to cough up more money to buy the gifts for Sunday, while I wait for Takealot to deliver the items 2 days later, phone in for a refund, fill in the form, wait for a courier to pick the goods up, then wait for a refund from Takealot. Who does this tedious and laborious system serve? Certainly not the consumer. (4) The order is being held because ONE item is problematic. Surely Takealot should ship the rest of the items instead of compromising the rest of the order on account of one item. Who does this serve? Certainly not the consumers or the sellers of the items that cannot be sold because of a problematic item that was not theirs. (5) There is no customer care number on Takealot website. There is only a form. I had to Google a contact number. What type of business does not offer its customers a contact number on the website? (6) I am now asking who benefits from the system set up by Takealot? It is not consumer-friendly. In fact, it makes no business sense to force consumers to go ahead with an order which has not been shipped, only to return it after delivery. Is Takealot receiving kickbacks from courier companies? Otherwise it makes no sense and its very frustrating, time-wasting and costly. Only not for Takealot.
