Wouldn't let me switch

Got the Japan Crate 3 month premium subscription ($30/month) for my daughter for Christmas. She got the first crate and said she didn't want so much candy and would much prefer the Kira Kira box ($29/month). Customer Service said no switching -- that only after we are done with the 3 month Japan Crate subscription they will subscribe us to Kira Kira. This was so not helpful!
