Do end-of-season rewards drop simultaneously??

I just logged on and received a "2018 honor level 3 ward skin" as an end-of-season reward. I did NOT, however, receive Victorious Orianna. I did end the season in gold 5 - which took a lot of games, since I'm not all that great a player. Is it possible that the Victorious skin is still on the way despite having received the ward skin already? If I did not receive the Victorious skin, what sort of recourse do I have?? Thank any repliers very much for your time.
