I've got some CS GO skins, and got notification that they have been sent to my Steam account. I haven't received them on Steam. URL for trading is good, I've received few other skins, and many times I got notification that I refused my reward. I really like this Dragon King skin for M4, and wouldn't want that notification that it has been refused. Can I do anything about it? Thanks in advance
