Indira Gandhi National Open University — Not responding to queries and is not providing me with Marks Card

I am a student of IGNOU m.com course and have been running pillar to post to resolve my issue and ignou is not resolving my queries and also do not respond either to emails or phone calls.

Issue: Marks card/Grade card/Provisional certificate not issued and not responding to queries.

I have raised multiple queries on IGRAM(Their official grievance site), written emails and also made several phone calls but IGNOU is not resolving the issue. The regional centre also says they have no role and cannot help.

I have passed my m.com final year and the marks are updated in the official website...it is only after promotion in first year that we are able to take exams for final year exams but my first year marks are not updated and they are not updating my first year marks for one subject and also they are not sharinig the marks card or provisional marks card.
