Can't create guild

I tried to create but it already exists, although I cannot find the guild in WCL at all. I can find one has the same guild name but it’s alliance guild. Ours is horde.

Our GM has now stopped playing, so we cant get the code. Can you remove the empty one so i can re-create or help me with the guild join code please.

Version: Retail
Guild Name: Dual
Faction: Horde
Region: US
Server: Tichondrius

Any update?

Your GM should have control of it now, just needed to update it.
