Okay, so if I understand correctly, a Nintendo Helpline guy told you that your concerns will be forwarded... which means nothing in the grand scheme of things - they won't remove the region lock.
I also can't help by notice the
"Japanese voiceacting DLC" request to on which I can only comment in the following fashion:
"If you don't understand Japanese, why would you even want that? If you do understand Japanese, why not buy the Japanese console and the Japanese version of the game? ;O;".
I sincerely doubt that either of those things will be released to be honest, the Helpline lads are there to handle customer complaints, they have no real power.
