Yes, calling them is pretty pointless. The call centre agents, just confirm what you already know and tell you about the 25 month processing time. It's much better to order GCMS notes if you want a more in-depth insight. Though they have dropped the ball with that too and don't send them out in time!I find no use in calling them anymore. It's kinda obvious that they see a different version of our tracker, but all info will be the same. They can only explain things that we can't understand on the tracker, and when we ask for an ETA, they're instructed to say the official "processing time" duration on IRCC website.
Realistically a routine citizenship application doesn't really take that much work, they could wrap it up in 1 month. I have no idea where the 25 month BS came from.
I have a friend who applied for British citizenship and the application took 4 months, and that's the norm over there...
