Same here. I also send 2 emails but no answer. I applied my pr file through new portal. I understand your situation.Same issue here. I received my login and password details on 1st Sep'2021.
Since then I have been sending them emails every few days and have also raised this issue via CIC webform 3-4 times already. No reply yet
It sucks because we've all waited for our PR for so long and now we're getting unneccessary delays on the very last step (i.e finalization of PR status). Lets hope they wake up soon.
