Investment fail big

<p>I have been saving with Assupol on policy Y ********** ********** 01, since 1 Nov 2016 on a 10 year savings plan with an instalment of R143,50 per month of which R13,50 of that is an admin fee, which they projected that as payout Amount of R29000+ on a 4% increase and R36 000+ on a 10% increase. I had an 10% increase on my installment per year at 1 Nov every year since.</p> <p>The maturity date was yesterday 1 Nov 2016 and payout this morning.</p> <p> </p> <p>I calculated the amount which I have been putting in this past 10 years and it calculates at R24 365+-,the amount Assupol paid out was R20 965.70.</p> <p> </p> <p>What I dont understand is how is it that the amount I have saved is more then the amount that they paid out. didn't I gain any interest on my savings and why is is that.</p>
