Annamalai University — Regarding my certificate

I have been waiting for my certificate since a very long time. All what my study centre says is to wait as of the pandemic, certificate will be delayed. I am a student who did my bachelors from Annamalai univeristy, (global-study center) bahrain and completed in the year 2018. All my payments are cleared and have recieved only marksheets of all three years and provision. As of now, i am persuing my Masters and need my certificate for the process. Sending mails to the grienience cell or all other email id's and contacting has been a waste of time since there is no reply. Please do something at the earliest.
