Riot please...

I've been banned for 20 extra days after my ban was supposed to end. I've been playing on my friend's account but he is back from vacation and i have no way to play the game without starting a new account( would seem as a waste since i wasted some money on this account and want it back), i would like 8000 rp as compensation ( its a joke) but i would really appreciate it if this could get resolved quickly , i wrote a ticket to riot support but its been over 30 hours and still no response ..
