Bangalore University — applied for marks, card but not received yet

Dear sir/madam
I have completed mca from t john (2019 passout) college bangalore affiliated to bangalore university. I have not received my 5th and 6th semester mark cards, provisional, convocation. Because of insufficient certificate my job opportunities was rejected. I have went many times with the request from college. Nobody was there to consider my issue. At least they should provide the markcard. They are really playing with the future of students.
