As per the information provided - (Period during which premium payable- APR OCT EVERY YEAR)
So the premium payment term is every six month .... your father had paid premium for 3-4 times means 2 years.

Now your question is will you get some money back?

As per LIC website -
Premium Stoppage :
If payment of premiums ceases after at least THREE years' premiums have been paid , a free paid-up policy for a reduced sum assured will be automatically secured provided the reduced sum assured, exclusive of any attached bonus, is not less than Rs. 250/-. The reduced sum assured will become payable on the event as stipulated in the policy.
In your case the premium is not paid for three years so you will not get anything.
But you can reinstate your lapsed policy, after paying the reinstatement changes to the branch, from where you had bought the policy.
