defective product 2

The received product is defective with respect to the slide. The party should be purple is yellow and vice versa and you can change as inter attachment to the spiral is not the same. So, the bends are not the same either, the slide is not usable because it lacks 2-3 cm so that it touches the ground and can be connected to parts of the multi track. It was a Christmas gift to a little boy, I'm very disappointed. Should we return the gift as a whole or can we get these replacement parts?
