That sounds frustrating. Maybe they are finishing reading another post before reading your PM. I like to savor PMs (since I don't get many). So I save them for last. It's nothing against the person who wrote it.
Maybe the person is thinking how to respond. Or maybe they just left. Try not to take it personally. I hope things get better.
