Do NOT buy from this booster. I have had several boosts done from him throughout the season, which all went fine. The problem is that he uses bots/hacks during games, which just got my smurf banned. He is the only booster, or the only other person for that matter, who has ever been on my account. DO NOT TRUST HIM.
I have attached a picture of my support ticket from Riot and their official response, showing a time stamp to prove this is not a lie
