If you have just recently transferred, like within the past 24 hours, you may wish to open a ticket or post on the Customer Support forums. I’m not sure anyone would be able to help you, but if they could revert the transfer, you could maybe take a new free transfer to Benediction, which is the one majorly Alliance server among the PVP destination servers Faerlina (Horde), Benediction (Alliance), and Whitemane (Horde).
Hope so!
