Yes, it was a mistake by the agent who processed my file; he incorrectly calculated my physical presence days, which made me fall short of the required 1095 days. Therefore, my application was sent to a special department in the Sydney office that handles such cases, but to be reviewed by an officer not an agent. To reach your turn, I had to wait 9 months. Finally, the officer opened my file but he also followed the same mistake made by the agent and cancelled my file, sending me an explanation letter that I was short on days, etc. However, I replied to him with a detailed explanation that he had miscalculated my physical presence days, which left me almost 200+ days short. He replied to me with apologies that it was their mistake and two days later issued a new C number with a new AOR, noting that my file had been transferred to the local office and should be treated as urgent. So hopefully things should go smoothly from here. The only frustrating thing is that I found notes about this issue on the GCMS, and I tried to inform them about it via the call center, web form, and MP channel, but it seems they don't read the messages - it's only one-way communication.
