So finally after 19 attempts, call got connected to an agent. Agent said file is not lost it is visible, and there is no indication or notes that said the officer needed additional documentation or anything but officer still did not mark your application complete. She said you will get your AOR only after whoever opened my file marks it complete or might request for additional documentation. I do not understand the delay in this.I can totally understand, getting to talk to an agent on the call is very difficult but you have no other option. Keep trying, you might be lucky in 10-12 attempts.
