Did not receive passport back from cpc ottawa / fedex

on 26th May 2020, cpc ottawa confirmed that my passport was returned to me. But the fedex tracking number never got updated. When i contacted fedex regarding it, they said they dont see any updates in their database (they havent received the package). Fedex asked to tell cpc ottawa to contact them and check.
cpc ottawa is just saying they returned the package containing my passport and now i should contactfedex for further enquiries.

The package contains my passport and its very important for me. I do not want to lose my passport.

Please guide me on what should i do in this scenario.

did u get it back? call Fedex and ask for it?

I got it. FedEx updated tracking and it was delivered next day. But earlier when I was calling to check with fedex, it didn’t have any info.
