This is quite possibly a way to be able to get a GM to show up to you, a GM actually teleported me from Felwood to Orgrimmar for me to check my mail, and then ended up "escalating" my ticket, he said he was going to have a specialist talk to me...
Still no response, been about an hour... so I will just post it.
1. I logged on and couldnt pick up 2 things in my mail, the icon was the red question mark, I could see the ammount in the bottom right, but when I opened it it said something like could not retrieve data or something...
2. I opened a ticket and flew off to do some quests (at this point, I can actually see them in my mail, I just keep it up to see how far I can get it to go)
3. GM responded asked me if I was using 3rd party program addons then told me to delete WDB, WTF, and Interface... (I know better, I just logged off my account for 5 minutes, read step 4 before you actually log out)
4. Before I did that, I told them there wasnt a mailbox around and it would take a few for me to get to one, so I asked if he/she could either make one for me, or port me to one (I ended up getting a port to Org right next to the mailbox)
At this point, I thought for sure I was going to see the GM and then the specialist thing was told to me...
My ticket says
"You have an open ticket."
"Your ticket has been escalated."
I have a screenshot of a few of the things that were said, but I am much to lazy to upload them... So if I wait for the response, I will edit the post, if not, feel free to experiment on your own.
