Thanks for information, do you know the contact number of IRCC New Delhi.
I think you can contact them by webform, there is no way to call them, because the number shown in the website is working just within canada. The best solution send them a webform, and wait for an answer, it can take a long time due to the covid19 situation. Hope you get some news about your application
 
They never respond to it. If your request is considerable then they will process your file and you will receive passport request.
