Bangalore University — not getting degree certificate

I habiba have completed my degree in the year 2016 with nmkrv college n from past one year i'm trying to get my degree certificate n i haven't got it yet,, every time i either visit or call at the office they tell me to call back after a month or after a week.. It's quite annoying to having been hung up like this for my degree certificate.. I'm still positively calling every week hoping i will get it somehow.
