Well, after all of
this, I managed to get one game done with my opponent. I won the first game and told him to challenge me when he's ready for the second one, but he didn't reply. I asked him two more times to continue playing and received no reply, as seen
here. Maybe he thought it was just a best of one and left, I don't know. I will wait for him for a bit more, but if he doesn't reply, I'm not going to wait around and will have to leave, meaning the best of three set will likely remain unfinished.
