Ways to do this:
1. When you call, mention it.
2. When you open a ticket, mention it.
3. Post in the general section of these forums and let they know.
4. Mention it to friends and guild members and ask they to take part in letting Blizzard know this is a issue.
This is not a Lightenhoof is gone, dying or anything of that sort thread. It's a acknowledgment of a on going issue that needs to be addressed.
