A random ticket thrown into the abyss might not get any traction, but I find a well considered ticket with appropriate instructions typically results in help. Sometimes it takes a quick ping on chat or finding the right person, but people are generally helpful in routing bugs.
I'm regularly pleasantly surprised when I file a bug for something on the other side of the company and get proper engagement on it.
If you know anyone still there, just have a peek at all the internally opened tickets about bricked Android phones. Their processes are...messy.
