I had a similar experience today. I have crossed 7 months and my eligibility is still under review with no ADR, BG check not started, only medicals passed. (AOR Mar 25)
Not sure if I am the only one who is getting these rude agents. he refused to share the status of criminality, security,etc stating that everything comes under BG check which has not started yet. He even refused to give me VO information stating that you should not reach out to them and wait for an official email instead. (Sitting with Sydney:CIO office which was mentioned by the last agent I talked to)
I am again given this random Dec 17 date which is the date after they will try to escalate from their end.
