Are you aware of your office? Also, did you check your junk email? The PPR email often goes into the "Spam" folder and you may have missed it.To add on, I am residing in Chennai, India. Is there any organization I can contact to enquire about my application?
You should email the Visa Office and also try contacting IRCC using the app called TextNow. Get a canadian number and then call 1-888-242-2100.
