Being mislead through a purchase on Takealot

Good Day, I have purchased Simply Comfy U Shape Pregnancy & Maternity Pillow- Full Body Nursing Pillow from Takealot. I ordered the item on the 27th of October 2022. I received a notification on the 3rd of November 2022 that the Pillow was ready to be collected. I went home and discovered the item was not correct. 2 of the staff from the back office at Takealot came to assist and agreed that the incorrect item was sent to me for collection. 2 other Customers was waiting to be assisted also confirmed that it was incorrect. The 2 Takelot staff assisted me with an Item return which was part of the process. I made it clear I want my item to be replaced with the item I have selected on the online Takealot store. The 2 Takealot staff advised me that I will be assisted. I saw on the 4th of November 2022 on email that I was required to return the item which was already done on the 3rd of November 2022. I called the Takealot customer care and this agent advised that I will received a credit and that they have no control over penalizing their suppliers. All I said please exchange this pillow for the item that I have originally purchased for. Again the agent said Takealot cannot take responsibility for item we as customer see as well as price. Personally I don't feel comfortable to purchase from Takealot online Portal that we customers are being mislead to buying an item and not knowing that the outcome would be different and again we buy with confidence that we will get the item we purchase for.
