Well, that's horrifying. Basically I was working from this person's timeline in a previous post:
"My family member was DQd 5/26, and we received confirmation of an interview appointment date on 6/6 for 7/28"
If I were in your shoes (and I might be soon...), I would be trying my best to contact the embassy. Please keep us updated!
Edit: maybe through here?
