An Unkillable Cheater Trapped Us In Ranked on 2 Accounts

My duo had been sitting in the lobby waiting for me to hop on, stressed out because he was literally one loss away from demoting. We finally party up, queue into Ranked hoping for a clean win, and run straight into a nightmare: a single guy controlling two accounts at the exact same time, both completely unkillable with godmode cheats. He refused to cap or end, holding the entire lobby hostage. After realizing there was zero point in feeding a dual-boxing hacker our sanity, the whole team mutually agreed to just close the game and take the loss. (w gemini)
