Awesome communication, top seller.
Leave them negative feedback.
I guess I could try to contact them again and see if there's any way to resolve this, but I'm pretty sure I'm just going to end up taking the L here.
The agreement was to trade codes. You didn't get a code, and you didn't get your codes back.
Is it your word against the other person's? Yes, but that is the nature of digital transactions. I suppose you could track down the other person's Steam account and see if they have those codes in their library, but even then it's not definitive proof. Note that this also opens you up to negative feedback from the other person.
You can also contact Humble support and say your link is invalid; they will deactivate the game and give you a new gift link.
