Pondicherry University — Im complaining about their mistake of information in my degree certificate and provisional

Pondicherry University issued my provisional certificate and degree certificate roughly a month ago where it was stated that I ve acquired 7.76 cgpa and mentioned 1st class. I have already received my consolidated mark sheet in which it was written second class. I recently discovered the mistake made by the university and went to approach them. At first they didn’t check anything and asked to submit my original consolidated, they didn’t get back and responded rude on the call. After again we went to check and they didn’t respond properly so I called many people to find help. Then they asked me to wait a long time and came up to say the mistake is on the other two documents the degree and provisional and asked us to bring and submit and they failed to give a time when I can get my originals back. I already told them I’m in a middle of emergency half way submitting my documents for transcripts and still they didn’t bother especially the engineering section. Now everyday we are going up and down to university to home leaving all the important work and they introduce new things again and again. This needs to strictly be taken action because as a student I’m being the victim of their mistake. And still go and stand to them who are disrespectful. Please employ more educated people or train them how to not make mistakes in important details of students or at least to respect and respond.
