noone here can help you with the order id.
File a support ticket.
what comes to mind tho: are you using the correct bnet account?
is VOH visible in your battlenet/steam account?
since it told you that your free trial is over i can only assume you switched back to your spiritborn, whos lvl 25.
do keep us updated buddy, make sure to check you arent using a gamepass account, while having d4 base and voh on steam or stuff ^^
