cancelled orders for safety 1st ready set walk baby walker expected

I placed two orders on the 17 June 2021 for a safety 1st ready set walk baby walker expected delivery date was 30 June 2021 , orders were cancelled on the 18th June 2021 by Takealot stating "We're sorry to let you know that we no longer have stock of the below item(s) in your order. We were unable to source the item(s) from our suppliers and have unfortunately had to cancel the item(s) from your order." I find this totally unacceptable as the safety 1st ready set walk baby walker is very much in stock as today (21 June 2021) it is showing on the takealot website with different price . This leaves me to believe that there has been gross negligence with regards to the pricing at the time I have made my purchase and now they are trying to cover it up with a stock issue. I expect to receive my orders for the price I ordered for because there is clearly stock available and estimated delivery date of 30 June 2021 is not yet passed
