regarding passport collection

[unesh]

Hi there! I have recently heard from Canadian high commission that i have been provided a residence permit and ask me to contact vfs office but they refused as they ask me for mail from canadian high commission. Canadian high commission in Delhi told me to flash back document but i am not sure what does that mean.And the passport was return back because it was undelivered on may. I contact Canadian high commision for sending mail so that i can contact vfs but i do not receive mail in 1 week as well. i am little worried if my visa will be cancelled. can i collect my passport directly from an embassy in Delhi?
