Query: arrived cracked

Ordered 2 units, 1 plastic container arrived cracked. Finally, after no response to 2 emails, called customer service and was told a refund will be issued. You must keep the cap on the bottom or the cereal does go stale, I like the design but would like to see a declining barrier on the top of the cereal that goes down as the cereal goes down to keep the air out.
