Often it needs to be bumped up the ladder. If you get a canned response, follow up. I don't like to speak ill of people until they deserve but 1st level support is really bad. I equate it to calling a big corp and getting some dude crammed into a shoebox in India reading from a script.
CS is a terrible job, every ticket is probably a complaint, so I imagine turnover is big at the first level. They just don't know the answers.
OTOH, happy people don't come to the forums to congratulate them on a job well-done. So the forums is the group that are unhappy. As best I can tell, there are maybe a dozen or so that hate EE as is. That's not a big percentage. Maybe many suffer silently but, unless they're sending tickets, CS doesn't know about them. And, IMO, you can't react to 14 people complaining if you have hundreds who are not.
