The lines do get rather busy, Gingavitus. Similar to a radio station though, keep dialing and you should be able to get through. Unfortunately only they can remove an authenticator off the account.
Keep in mind that you will need to fully verify the account and provide one of the following:
Digital serial number for the Mobile Authenticator
Classic World of Warcraft CD Key
If you have misplaced your CD key or did not write down the digital serial number you will need to fill out and send the following web form to accountservices@blizzard.com:
