IB is open now. If you don't want to call overseas, you can contact the help desk via chat. At this hour all treasury functions will not be available but they will be able to detect what happened.
note: I may not have this exactly correct but I think under CT law, dormant account holders must be contacted periodically. If the email and phone numbers on the account are incorrect and the account holder is unable to be contacted, the account could be restricted.
