Can't see/join guild

Character name: Blushberry - Mal’Ganis US
Guild name: M Y T H I C C - Mal’Ganis US

The guild is on manual in WCL and I was given an invite to join the guild on WCL, and reclicking the link will say that I’m already a member of this guild, but I can’t see the guild on my WCL home page and the WCL uploader so I am unable to log for our “milk” raid team for our guild page and so I have just been doing personal logs for our raids.

The GM or an Officer need to promote you.

In the in-game guild or in WCL?
