The opponent was leading 3-1 until the 88th minute, when I scored a goal. After that, at the 90th minute I scored another goal, making the score even, 3-3. As the ball went pass the goal line, the opponent quit (proof is the screenshot attached to the protest).
As the rules state, if the opponent quits before the final whistle, it means that he forfeits the match, resulting in my victory.
He dose not want to accept neither the 3-3, nor the 3-0 score. I would like the admin to bring justice to this unfair behaviour.
Even more, after writing the protest, the opponent eliminated me from his league. This is clearly against ESL's rules.
