How Do I Get A "Summoner Icon" For Partcipating in 2016 World Pick Em?

So today, I filled out my bracket for Group A-D. However i still haven't received my Summoner Icon. In the "How To Play" Section it clearly states

**"Participate in Pick'em by filling out your bracket for either Group Stage or Knockout Stage, and you will earn this summoner icon." **

I have filled out my bracket but I haven't received my summoner Icon either i have to wait 18 days to get it? or i'm supposed to get it now? I don't know but please help me on this issue. I would really like the Summoner Icon.

[Proof I filled the Group A-D]

PS : I'm new to "World Pick Em" so I don't know if i'm supposed to get the summoner icon today or another day
