I was following up with Mississauga office since months to schedule oath ceremony for me & my kids, as I had received invitation from Citizenship test from them. Now when I finally got invitation for oath it is from Scarborough office. I applied from Mississauga, however I had initially landed in Scarborough after getting PR. For my spouse entire processing happened at Scarborough office.
So if you don't see progress despite following up with genuine reason, confirm processing office.
