Here, I started playing as soon as the list was announced. Then the opponent postponed, then he wrote about having to meet a friend. Then he had other obligations, which were more important, and yes, he told me that the deadline was until the 19th and there was still time. There was no reason to doubt his words, and it seemed logical.
I'm not shifting the blame onto Redii, not at all; it's entirely my fault. I'm just trying to explain how it happened. In the future, I'll only participate in Tournaments under the condition that I immediately ask the organizers to set a specific date for my match with the opponent. And thank you to the organizer for this Tournament; it was just difficult to ask via ICQ when I was online the whole time. We can get distracted for our own reasons, but why bother with this, right?

It's much easier to criticize the organizer's work when you've been rightfully kicked out of the Tournament.
