Very patient and understanding. Would be happy to trade with them again in the future.
He send me direct link on steam gift https://store.steampowered.com/account/ackgift/B7B2D5F82AB87901?redeemer=gamesforwin3%40yandex.ru. I pressed on it and there was window with request to accept or decline gift (green button DECLINE) (see screenshots) https://ibb.co/T05HHjS / https://ibb.co/V9ZTM7r. After that there was a message that gift was declined and was returned at soldato.bely inventory. Who is soldato.bely i dont know, maybe this is schastliv4ik second account or his other name in steam. The point is that gift was returned to the person who send me that gift and no way that it was ended in my library or inventory. And now he disputed me for no reason because i declined gift from third person... And i dont know where that gift now, thats not my problem anymore.
