Madurai Kamaraj University — Convocation Certificate not received Applied in Oct 2020

Address:

Palkalai Nagar, Madurai, Tamil Nadu, India - 625021

I have applied for convocation in Oct-2021 and still I have received the document. I'm trying to follow up with the concerned team however there is no response. Wrote multiple emails to the directorate and made so many calls but no one is ready to reply or answer my calls.
This is a very serious concern for students who are not from the same state.
