I bought a GTA V gift for 20 tf2 keys here: https://dispenser.tf/trade/161817/
But the gift was reinvoked after 2-3 mins, that shop is now closed because the user is banned.
I wrote a ticked to Steam Support but I think they won't give back that gift, so I should ask the shop owner to give back my keys or what? (I know his steam)
Pls help :/
