I got cursed please help me Riot

So I'm currently trying to get lv 7 as Sion. I recently got a token and I have been playing Sion nonstop in order to get the other 2 tokens as fast as possible. However, my friend cursed me to never get a S or higher on Sion forever. I just played a Sion game after he cursed me and I was against a Ignite/Heal Olaf top and was camped the entire game. Is there anything I can do to receive lv 7 tokens by Riot directly? Or at least obtain a number for a Vodoo priest?
