Date of birth correction

Dear Sir,

I was born at home ( not at hospital ) & my date of birth was wrongly registered by my parents with local authority.

But my passport, school records & church records has correct date of birth.

Now I am in urgent need of birth certificate from Panchayat / local authority.

When I contacted local Panchayat Registrar, he told me that he wont change it any cost even if you come with First Class Magistrate order.

What should I do?
