Passport received by IRCC New Delhi on Mar 17, still no response

Hi all,

I submitted my passport for COPR stamping to IRCC New Delhi, but I haven’t heard back anything from them.
I have since written multiple emails to them but I’m not getting any response.
We are pretty close to our COPR landing last date, April 22, and not sure how to go about contacting them to speed things up.
Has anyone been able to get in touch with the New Delhi Mission?
