Yes… here:
To be honest… I don’t think there is a lot that can be done on the forums.
Any account issue normally requires a ticket to be resolved… so your wife and son, as well as yourself, will likely each have to send in a ticket (one ticket per account). Use the following link https://us.battle.net/support/en/help/contact/1941/ticket
and fill-in the details as best you can. Use the “Description” box to explain the issue – provide as much details as you can.
The response time for tickets is long at this time… you may have to wait several days for a reply from Blizzard – a week ago, the response time was about 7 days. You will need to be patient.
Good luck with this.
