Thanks!
Sorry for replying late!
No, I didn't receive any such letter from IRCC, but I did send an email to
passportsubmission@vfshelpline.com as per the IRCC new notification on November 13 that we have to contact the VFS glogal to arrange two way courier service for passport pick up.
I did contact the VFS global via email (as their telephone line is non operational) on the same day, and it was by continuous reminder emails for last couple of days, I got the payment link today. I paid the fee and got the AWB number with two forms (Courier/SMS form and Consent form) after an hour or so. As of now, my passport pickup is scheduled for tomorrow i.e December 02, 2020. Let's see if the courier guy show up tomorrow or not.
I would like to add one more thing, I had mentioned two addresses while sending an email to
passportsubmission@vfshelpline.com for confirming two way courier service. I did this because I doubted that my residential address doesn't come under the blue dart service regions, so I provided alternate address of my work place of which I was certain that blue dart service is available here. I believe the people who had provided non-serviceable address, got another email from VFS to either provide alternate address or some other location where the blue dart service is available. So, I think one should check before providing the address whether Bluedart is providing service there or not and if not sure provide two addresses.
