The main thing is not to withdraw from the tournament; the situation is certainly not ideal, as there was still more than a month left until the end of the group stage, but since Los confirms the technical defeat, it is your personal right to review the game. And for Sevan, somehow arrange a replay, and if he sees that you are really playing well, I think all claims will disappear.
Well, saying that I'm really playing well is a bit of an exaggeration, but if the situation allows, I can take full advantage of it.
sevensanu - you are Sevan, and Sevan_80 is also Sevan -))
Does the technical defeat still count?
