Update: did DNA and worked immediately. Oddly enough Amazon JP's site didn't direct me to the live help customer service thing, just asked me to send them an email.

Too easy.

A job well done Indeed on your end.

All they asked me was if I used DHL's "On Demand" service (I have no idea what that is)

It's an express delivery service, whereby the package Is assigned to a dedicated carrier driver to ensure It makes Its way to your address without complications. You also have the option to be notified by text or email pertaining to how It's travelling through their network.

I don't know why they asked you. Logic has It, DHL would have a record of the type of service(s) assigned to their shipments.
