If you are abroad, you should call to +1-613-944-4000. Calling this will reach to global affairs Canada. but unfortunately they are not taking any more calls from abroad which are seeking enquiry about visa, study permit etc. I tried calling them and it ended up disconnection. You may try calling and check this out.
If you are in Canada, you should call to +1-888-242-2100. You will be able to easily reach to IRCC directly and ask your queries on your application.
If you are abroad but you still want call to above number (+1-888-242-2100), you should install textnow software link here. I was helped by a fellow member in this forum to use this software in android or iphone. Download this software in your phone and install it.
https://youtech.ooo/textnow-mod-apk/ Once you install it, you should turn off your location mode in your mobile, and choose the don't use my location option in the beginning and provide this area code number 613 in the area code option. 613 is the area code of IRCC in Ottawa. When done with this, you will get few textnow numbers with one of which you would able to call IRCC.
I tried installing it, but it doesn't work for me due to latest version of android. You may try installing it if you have android older versions I think.
Give a try and see if it works.
