Mumbai University — No getting leaving certificate from college

Address:

Mumbai

I have successfully completed BMS (bachelor's of management studies) from one of college affiliated under Mumbai University. When I asked to issue leaving certificate (which indicates that I have successfully completed graduation from your college in this year and mention date of leaving the college) but the college has refused to provide me the same, they said that they will provide me the same leaving (of XIIth) which I have submitted in college at the time of getting admission.

I request you to kindly look into this and get it resolved.
