I won the Screamers Tournament and didn’t get the Ultimate Scream Item

Hello guys, I just won the Screamer Tournament and I didn't collect the group rewards on purpose thinking I would be able to collect the rewards for winning the tournament yet it says I didn't even win it. I am playing against the sweatiest players and don't get rewarded. Now I am collecting the other things because I want to gamble. Please give me my Screamer Evolution and my 82+ x7, thank you very much.
