Same when I bought a large toy that needed assembling (although it was not Carrefour). The packaging was already trashed so I asked repeatedly if all the pieces were there as I did not want to empty the whole box on the shop floor. repeatedly they assured me everything was in the box. But low and behold when I got it home important parts were missing like the nuts, bolts and screws, can't say i was surprised but annoyed as I had asked the question many times and was given assurances. As you can probably tell, I took it back to the store. It is no wonder they do not give refunds here, they know they are selling a shoddy product half the time and will need to give refunds a lot. They really need to change the consumer laws and stop screwing the customers
