Osmania University — Not issuing my provincial certificates

Address:

Hyderabad 500007

I have studied 1st year b.sc degree in a private college attach to osmania University, after I got job I transferred my b.sc 1st to b.a 2nd year in PGRRCDE, OU.
My 2nd language in B.sc 1st year as sanskrit and I wrote telugu as my second language in BA 2nd year, the college had misguided me and made me to write 2nd language as telugu.
I passed all the 3years and got short memos from the university.
Now, when I applied for the provincial certificate they rejected my request and saying me write the sanskrit exam again.
I request you sir to please resolve this issue and provide me the provincial certificate from PGRRCDE, OU Hyderabad 500007.
