Alagappa University — Degree certificate Not being dispatched

I have completed MCA in 2018 and received the provisional certificate in 2020 and ever since I am requesting the COE, Alagappa University for the main Degree certificate which is required for me to produce in my company. But the response I got is that that degree certificate will be released after convocation.. I am tired of asking as to when is the convocation and what is the process for it but no luck.
Kindly understand the problem of we students who trusted your organisation and invested our time and money for education. Help me get my degree certificate please. Appreciate some action for god sake.
