What can we do if LIC (Life Insurance Corporation) of India does not maintain our policies properly?

I have 7 LIC policies in SSS(Salary) scheme. LIC people are not maintaining the policies properly. Though the amount was sent, there are showing gaps in their soft data. Later, they are not updating properly. I gave written complaint last month. one month passed. LIC could not regularise my policies due to staff problems and technical problems, they say. What can I do later? How to complain further?
