Not happy with the service

I bought a 208 Super mega children's art set on the 7th of December 2022, I was told that it needs to come from JHB, and it will only arrive on the 12th of December after paying and being very excited, I waited, on the 11th I got a notification to say my order is ready for collection I drove all the way to Richmond to collect , took it back home to open it up and give it to my daughter to find out it is the incorrect product , it was an 150 art set and not the 208 I ordered , no one said anything or apologized , I emailed take a lot immediately to ask for this to be corrected , I told them that my daughter can keep the item I just want the difference of the two items as a take a lot credit or a refund as this was an error on Take A lot side. I was told the item needs to be returned if not returned then nothing can happen and that is the policy of take a lot, I just want the difference paid back or credited is this too much to ask for.

I am not very happy with this service; how do you just take a present away from a child that was sent incorrectly from Take Alot
