This drives me absolutely batty.
I recently had a case where after two weeks the tech says he found a solution and sends me an article. Problem is I already mentioned that article and how it doesn't solve my probem in the very the very first comment I created the same day I opened the case.
I actually posted to the case, "Please don't take this wrong, but did you actually read all the comments I've created?" Never did get a answer to that question...
