Darkmoon fair treasure not appearing

Hi everyone, I tried everything with Blizzard support, being in a compatible country, be over 18, refresh my account, disconnect reconnect, restart the game, desinstall and reinstall, … Nothing changed I still don’t have access to the Darkmoon fair treasure. It is not the actual one that we have today, It has been the case for all of them. Can someone help me ?

Kind regards,

Edouard
