Annamalai University — Degrees certificates and marksheets not provided even after multiple reminder

I have been following up regularly for my MBA marks card & certificates, however the university has not shared it yet. My immigration process has been impacted due to this, this was also informed in all the reminder still the university is not bothered to help. I would like to officially raise a complaint against the university for traumatising the students who have dutifully paid fees on time.
