If there was an attempt, I might (but I don't promise) ask for clarification on any unclear details. But if a person doesn't even try to provide a time when they are available to play, then, as the tournament organizer, I'm not interested in spending energy on this, asking something like, "Oh, bro, you forgot to write when you want to play, come on, maybe you'll write? I can wait a little longer" - it's absolutely uninteresting, and that won't happen. If they didn't write, it means they don't know when they can play, so we'll skip that match.
I confirm this unequivocally.
And yes.
I AM NOT confusing anything.
