Christian Medical College — About birth certificate

Address:

CMC Hospital Vellore Tamil Nadu

This is Sindhu. I went to CMC hospital on 5th February of 2022 for birth certificate details and did the formalities like filling application and try to submit in room no 3 at MS Office . I was born in CMC Vellore but I'm not aware of the exact date and year, Why because I lost my parents at my very early age at 5, now I need my birth certificate for my passport and came there and asked them in a very polite way and expressed my problem but the answer I got from the person is very rude . I only know my parents details and mothers Hospital number. The details are as follows
MOTHER;DHANA LAKSHMI [Hospital no 352000B]
FATHER; SUBRAMANYAM REDDY
ADRESS; Nangamangalam Village, Gudipala Mandalam, Chittoor District
These are the details I known I hope these details helps in Fetching my birth certificate
