In game shop black box

for the last 3 days now I have been trying to use the in game shop to transfer a toon to another realm, keep getting the black box appearing after I select what realm to go too, this happens with wow tokens and also name change.
So blizz will probably link this thread with the troubleshoot page, I have already reset the ui, disabled all my anti virus and firewalls, restarted the game, reinstalled the game. Also, it seems impossible to open a ticket, connect to live chat or even ring blizzard to have this issue resolved. any ideas on how to fix this from the community would be great. Thanks
