I received the same e-mail from the embassy stating the exact same, however I called DOS the very next day only to be told that an interview date and time had already been scheduled. The embassy just sent me an email confirming the appointment last week. So definitely follow up with DOS as that email appears to be a standard response, while your interview has probably already been scheduled.
