So just to share the greatest of my tragedy this graduate admission season (and oh there are many, and probably many more to come): two days ago I finally was able to access my voice-mail system, and the first that I heard is from CCA to set up an interview. It was from many weeks ago, and I've nervously checking up on their website for my status almost everyday all this time as it's one of my top choices.
When I finally reached the person who called me yesterday, he told me at this point he have to talk to people about what to do with my situation and get back to me (hopefully, he said). I totally lost my chance didn't I T______T
PS: I remember that I saw the missed call from the 415 area code and specifically suspected of them, but the number he called from cannot be called. I talked to someone else from CCA and she told me that she doesn't know that number and the area code is probably just a coincidence, after I heard that I dismissed it and put off fixing my phone, oh so very very stupidly.
