Order cancelled due to the Item not being in stock - when it actually is!

My last experience with Takealot has left me very disappointed. I placed an order for a laptop with an expected delivery date being given as 13 June 2019. Two days later the expected delivery date was revised to 18 June 2019 due to stock issues – which I have no problem with in concept, as stock shortages happen even to the best of companies. The next day the order was cancelled and the customer service agent advised me that they are out of stock of the specific laptop – which is inconvenient, but also understandable. But then, while looking for another laptop on the Takealot website immediately after receiving the cancellation notice, I stumbled upon the exact laptop I originally ordered, but at a higher price. I realized two things: firstly, that the customer service agent **** to me when he said that the item is out of stock and, secondly, that Takealot shifted their supplier issues directly onto me, a very loyal customer who have spent thousands on their website – ever since the good old days of Kalahari.net. I do not appreciate being **** to, nor do I understand why my order was cancelled when the item is in fact in stock. At no point was I advised or notified that the order is conditional upon the item being available form a specific supplier, in fact I couldn’t care less who supplies the item I ordered to Takealot. Unfortunately I was refunded with store credit, and was forced to buy a replacement laptop from Takealot (let’s see if this one actually arrives!), but I will definitely think twice before buying from the website again.
