Riot games support email address or live chat help needed

Does anybody know how to reach out to riot games without submitting a support ticket, whether it is through email or live chat? Somebody hacked my account and is playing games on it but I don't want to open up a ticket so that they are aware I'm trying to fix the situation. I have all the proof I need to verify it is my account but I can't find a fast way to get support from Riot. Any help is appreciated. Thanks.
