Riverbed...the software cost USD $120,000+ and their support was horrible.

Tickets would go unanswered.

Their documentation was pretty good but there were parts that were wrong and they would not fix it.

They would usually close an issue because it was opened by someone else 5 years prior and hadn't been fixed.

The several years I used it their releases consisted of no tangible code enhancements.

Several times we provided very simple reproducable issues and there response was basicly "just don't do that".
