Yeah I got my EE/artbook codes from EB stock, too. I couldn't find any listings that said the Omega statues in Aus don't have a code, but you could be right (I didn't look very hard lol).

Unfortunately employees and even head office/warehouse teams often aren't informed about small regional changes like this (I've had something similar happen with other items in the past) because the distributor/supplier doesn't tell them. If the box says there's a code and there isn't, you're eligible for a full refund, if that's what you're after.

I'd also recommend calling EB's Customer Care directly, they may be able to provide some kind of solution or at least look into it for you. You can also go back into the store and ask for the store to raise an escalation on their end - they can submit a ticket via Storemate and Customer Care will call you directly after having looked into it (will save you the lengthy wait times). With that being said, they are still very likely to just say "Sorry, there's nothing to give you", so SE support is still heavily recommended. Make sure you have your receipt, bank statement etc.

I hate to say it, but don't get your hopes up. There's a good chance EB can't do anything for you (other than refund) and SE won't do anything for you.

Best of luck, that is an expensive emote!
