First off thank you to the customer service team, we purchased this puzzle for my son it arrived in time for his Birthday which is New Year's Eve. Upon completion there was one piece missing, we looked all over and couldn't find it. Contacted the company and Victoria walked us through the process with a couple questions. She asked we look again for the piece, reminding us to check the bag and box the puzzle comes in, and requested a picture of the puzzle in its completed form with the piece missing. She asked for a day to go over it with her team and 24 hrs later she messaged stating a replacement had been sent. A few days later and the puzzle arrived. The puzzles are great, durable and challenging. The company is a class act. My son has his eyes in another one already and we will definitely order from them again!
