Behavioral restrictions...

Not so recently I was banned from League because I was doing pretty bad one game (not on purpose... duh). I went 0/15/0 as Riven, and have since stopped playing the champion. I was banned for intentional feeding (this was the first game I have ever done so bad). The ban was on April 9th and was lifted on April 24th. That means it has been almost 1 whole month since my 2 week ban. I have been getting a message telling me I can not earn rewards due to previous behavioral restrictions. How long do I have to wait until I can start earning loot again? #FeelsBadMan
