You are ineligible to earn loot due to previous behavioral restrictions.

Hello guys, so last 6 months i've been trying to be a good player, dont flame and everything. But for some reason i still cant earn hextech rewards its really anoying that i cant earn rewards after i played like 100 matches trying to be nice person. Last time i was punished it was before summer for flaming my teammates... Is there any way to get this over faster?
