How long has it been? And did you open a ticket or call anyone? Sometimes you don't get things back, because a former guildmate didn't a while back.
I was exploring and running random heroics last night and I got my first penalty for leaving a party made in Dungeon Finder. Is it always a half an hour? That's kind of steep, but it was a half an hour put to better use exploring than listening to one of the members bicker with the tank over what gear they had. (Granted, dude was completely in blues, but still, it's more annoying to fight about it than actually letting him try.) Anywho, I'm halfway done exploring everything. Northrend and Kalimdor are completely done so now I just need to finish parts of Outland and a lot of the Eastern Kingdoms and I'll be Meabh the Explorer.
Also, I have to say, playing with a few people is so much more fun than playing by yourself, even if you're not doing things together. I like having a guild again.
