Don't be insulted because i don't wanna explain myself, i was probably joking anyway.
Don't count on getting any help. You'll probably get a reply with instructions on how to take screenshots on PC and Mac. Then you'll have to reply to that message explaining it all over again.
Then, if you're lucky, you'll get a response saying they can't help you and you should be more careful when purchasing. Gotta love Steam support.
You're supposed to be able to get a refund on a pre-order but seeing it can take weeks to get an answer from Steam support, they most probably won't respond before tomorrow (and even if they could, they would probably just wait it out and then tell you it's too late).
Your best bet is to sell the gift to someone for less money than what was paid, then buy the upgrade from Trion.
Yeah - I've only had bad experiences with Steam support...
Steam does normal do no refunds but if iam correct they do refund pre orders !!
Copy paste.
