Karnataka State Open University — complaint about degree certificate of b tech

Hello sir/ma'am,

To whom so ever it may concern, i completed my b. Tech (Mechanical) from ksou in 2014.
My enrollment number is 111071lbtme0488.
Since then i have been waiting for my final degree certificate. I have each of all semester's mark sheet also have provisional certificate of degree but don't have final degree certificate.
I have approached my study center several time but i haven't received proper information. I have called ksou many times in these 4 years but not pick up my call.
It's my humble request to issue my b. Tech degree certificate, as i need it urgently.

With best regards
