Hi
@SmzAmir I was struggling to get through to IRCC for a few months. However, I have been able to reach them using the following steps.
1) When asked for UCI press 2
2) When listening to the Ukrainian and Afghan message press 3
3) Press 3 again
4) Finally press 0- if it goes through it will go through to PR card line- then ask to speak about your TRPR application they transfer you.
Try again and again till you get through. Hopefully it works for you.
