Emily, Customer Service
Thanks for your review. We're sorry to hear that you've had a frustrating experience with your advent calendar.
We take the quality of our toys very seriously, so we have tons of machines and people that work to make sure everything's perfect. It is incredibly rare for this sort of thing to happen, so we do always want to hear (through reviews, or contacting us at LEGO.build/Service, however you like!) when something does go wrong.
If there is something missing, we do want to make it as simple as possible for fans to get the parts we need. That's why we'll always direct you to LEGO.build/BricksPieces, where you can snag those pieces easy-peasy without having to call or email us.
