Mistake in date of birth in my LIC Bond Paper

Location/place: India

Name of company/service: LIC india

Dear sir,

I am Manish Kumar. I have taken a Policy ( Jeevan Saral ) on january 2010. My Policy no. is 516643070.
Sir, there is a mistake in my date of birth. I have given my age proof as 20/06/1989 but in bond paper they write 28/06/1989. There is an error in my date. So please do something to correct it.
I contact with my Agent but I didn’t get any result. So please sir tell me the correct way to solve this problem. I am very thankful to you.

With regards
Manish Kumar
