Question for INSTITUTE OF HEALTH CARE ADMINISTRATION

I have done PG DIPLOMA in Hospital Administration and also in Nutrition and Dietitics in 2001. My enrolment numbers are 18-150 and 18-151 respectively. Since i have changed my residence about 7/8 years ago i am able to find my diploma certificates. Is it possible to issue duplicate certificates as i need them for a job. Kindly revert on my email address as i am unable to contact over telephone.
