Actually, I had already said goodbye to the Pyra Forum. But I know no other way how else to reach ED. It's been almost 4 weeks since I submitted a refund regarding my Pyra pre-order via the official ticket system on dragonbox.de. No answer yet. It would be nice if ED at least serve his official ticket system from time to time.
FYI: The complete ticket content was sent back to me by email. Of course, unencrypted. In the ticket content, I have provided personal information:
Complete name
Order number
Bank account
I'm very upset about such an approach. I just used the ticket system because of its secure transmission (https).
