I've told the various teams that I wouldn't have to phone anyone if they updated the ticket. When I see a ticket that has not been updated for 2 months, there's no way I'm not phoning the assigned person.
Problem is that, even when I was a f/time IC, we hardly ever update the ticket unless we feel we have made progress. An update saying "Chased bug with no success $TODAY, requested $SENIOR to consult with me on this" feels like a worthless ticket update, but from the client's PoV, this is valuable info - it means that it hasn't dropped off our radar, we haven't forgotten about it, etc.
No one bothers to read/understand anything until the very last minute, then they realise “oh shit this won’t work in this scenario, and it’s always a showstopper”…
Literacy skills have been falling and it shows up in testing of a lot of different countries, and it basically lines up with the arrival of iPhone/Android(or real smart phones).
