Volks not responding to emails?

Has anybody had any issues with this? I've been sending emails to Volks' address shopos@volks.co.jp but have not had any feedback about my Ranka order which was paid in November. It hasn't shipped yet and I was wondering if they were having delays. Thanks.

You may already know this, but here is the current delivery schedule.

Not sure if you can get any more information by logging into the website store and checking your pre-order.
