Simply save sbi card reward point redemption

[Azadirata]

I have a simply save sbi card with 7000+ points. The vouchers i get are undervalued (against the points to rupee ratio) and also not useful for me to use. Is there any other method to tranfer the points to cash in the same value(0.25₹for 1 point). Or is there any way to raise the value to more than.25 per points
