I called IRCC before when an immigration consultant scammed us for our first application. I tried for 2 weeks and got so fed up i took a day off of work and spent 4 hours calling about 100x. I finally got through and spent an additional 2 hours waiting to get all the answers I needed. They're brutal! The Gcms notes take sometimes less than 30 days that is unless your getting comprehensive notes.
