It went through but the lady told me the other ways of approaching them: asking someone else in Canada to call 1-888-242-2100 for information or go to the nearest visa office for help. The +1 613 944 4000 would probably not be working any more, quoted from her.
Saw this in another thread. Let me know if it works.
To call IRCC from outside Canada do the following:
+1 613 944 4000 (for an agent: options 1,2,1,2,1 ... then 0 to skip the message)
