Takealot taking consumers for a ride

Ordered a Samsung qled 75inch from Takealot's app on the 27th of December on a promotion. Was informed yesterday via email that the order was cancelled due to no stock available. Phoned the supplying company directly to find out whether they do have any stock issues, they don't and have the specific make and model in stock. Went on to the Takealot app again and clicked on the product, it is available but now at an increased price? Phoned Takealot, the agent on the phone also said that he can see the item is in stock so he also doesn't understand why it was cancelled on the promotion price. Second order cancelled also this morning due to stock not available? So now I don't know what the heck is going on regarding this. I will be reporting this matter to the consumer tribunal tomorrow if item that is in stock is not sent at the original ordered price. ***
