Appeals Committee. Disputed situations in tournaments.

I have the impression that this particular tactic was indeed the trump card in my opponent's hands. The fact is that I often have very unstable internet, and on average, in one out of three games, problems inevitably arise, and my opponents in the games can confirm this, as I don't really have close friends on Heroes of Might and Magic. In the previous game, things weren't smooth either; at the scheduled time, I suddenly experienced glitches for about half an hour, and I was close to a technical loss, although I had a significant advantage. And Dark was stalling the game, both that time and this time, counting on problems, as I now think. (I have proof, by the way.)
And now I have connection problems again; it's the perfect time. Let him first tell what happened that day, on Sunday, and then let's make some assumptions about the green hero when the internet was down. Not only are they accusing me of cheating, but also of being stupid.
Yes, I don't understand programming, connections, networks, routers, and so on, but if I were a liar, I would have enough brains to turn off the Wi-Fi, saying that the children were playing around. (This is how our Western Heroes of Might and Magic players like to make things up.)
P.S. And saves before a battle are not as reliable as my GM1 save system after a crash, because you can lose in a game, crash, and continue the game before taking the city.
