Takealot cancels my order and increase price of book without my consent

I ordered a book on Takealot #*** and paid for it on the 11th of May 2023. I have waited months for this book. It was for sale for R325. On the 17th of May 2023 I only received 2 of the 3 items I have ordered. Needless to say the same afternoon I received a notification that Takelot has cancelled the book, which was now selling for R399! This is not acceptable as they can't just cancel orders when and how they like, and then increase the price!!!! I am hugely disappointed by this company, and will definitely not be buying from them again! I heard rumors that people were complaining but now see it seems to be true.
