@VFSGlobal@CanadainIndia I had created a login account for processing my student VISA to Canada. I created the application for biometric appointment at Kolkata Centre and submitted my biometrics.
This seems to show that somehow VFS GLobal has deleted my email account due to which I am unable to raise a passport pickup request. I would like to mention that I had opted for the premium passport pickup service at the time of submitting my biometrics.
