[2019] No response from Ubisoft Support after a week

Hey e11evvenn, welcome to the forums.

Sorry you've not received a response from the support team. They are extremely busy during game launches and sometimes can't answer tickets as quickly as they'd like to. Have you tried contacting by live chat?

With regards to your question though, yes, you could try pre-ordering via the Ubisoft Store website if you haven't tried that already. As for a refund for your failed order, that will also be something that support can help you with too so please don't worry.
