LIC Policy (Growth)
Not getting benifit of my policy

I have taken a policy of LIC (Growth) no.175816638 in Dec I have deposited Rs15.000/- per year, Now after 5 years the agent Say's you will get Rs73.000/- of this policy but before of this policy he says lots of benefit of this policy.

So I just want to know that if I have deposited Rs75.000/- in total, Then how i will get less then that amount, Where is my benefit?
