I agree with Orylia here.
Here’s a convenient link to get assistance:
https://us.battle.net/support/en/help/product/wow/166/167/channels
Call back service opens at 7AM to 10AM California Time (10AM to 1PM Eastern). A limited window to be sure, but try to get in right when they open and someone will call you and (hopefully) get this all fixed up.
Sorry for the difficulties you’ve been having. I hope it goes better today.
