Need help with stolen account

My account was stolen on the 18th, I got it back the same day. It was just stolen again though and despite the emails and tickets I have sent nothing is happening. I can still use my account on the forums since I was logged in. One player keeps playing with the hacker though, I told him he was playing with a hacker when i got my account back. Checked and venanthus is still playing with whoever has stolen this account. I desperately want this account back. What do? Riot support wont get back to me and I am not receiving reset my password emails. Could I get my account reset with a text message?
