I have purchased a name change, but when I go to use it, it says the name I want is not available on my realm. I have tried adding that character as a friend on both an alliance and a horde character on the same realm, and it says “Player not found.”
How can there be nobody with that name, but the name is unavailable?
Just because it doesn’t come up when you try to add as friend, doesn’t mean it doesn’t exist. It may be a low level character that someone else has saved.
