Query: Disappointed

I was so excited to find this advent calendar! It looked just perfect for starting a new tradition with my two children. They are 3 and 6, so this looked like a great way for them to count down to Christmas and relate to the Christmas story. However.....I was sorely disappointed when it arrived. The metal back was warped, and one of the doors has a big crack in it. I tried to request a replacement from Amazon, but they are sold out. My only option is to return it for a refund. Very frustrating, with just two weeks remaining now, for me to find a new advent calendar.
