My account has been compromised and I'm not getting a single response.

Please, my account has been compromised by a simple phishing act, making me try out a game that was supposedly on steam and posted on GameJolt (A webpage I've always trusted for years now.)

I've tried contacting with support via support tickets, both in english AND spanish, but I'm not getting a single response.
Also tried contacting via twitter, spamming like a madman... But you're deciding in answering tweets of MUCH minor importance instead of mine which is HIGHLY compromising other users as we speak.

I need help. Please.
