Guys,
One thing you need to make sure is your address is correct on the file, when you call to a CIC agent for your PR card status.
There are chances the address might be different. Like in my case, I am through a IT company when I first entered Canada, when I called CIC few days back first time, they said I have the address of British Columbia, then I realized it was my company's attorney's address who dealt on my behalf for my WP extensions. Then I updated the address on my file by the agent and requested him the card should be on my home address at Ontario.
It seems during landing the address which you confirm that hardly gets updated or applicable for your PR card or may be for some cases.
Thanks
