Hello,
I have purchased a name change today, the money has been taken from my account and the name I chose was available.
However, the name is still the same - I have restarted the game several times and it has now been around 3-4 hours.
Please advise.
Have one of your friends whisper you on your OLD name. If they get a “Not found” error, then your name change worked, and the problems are because your old name is being cached by your client.
If that is the case, its usually fixed at the next reset.
I would say try deleting your cache folder. It could also be addons storing your old name, so try a UI reset by moving the WTF and Interface folders to another location, you can move them back later. You can tell it works as you get the intro movie.
