Is anyone else annoyed by the taxes on PayZapp vouchers? I’m looking for a better way to spend my points — maybe on bill payments or travel. I want to find a redemption path that doesn't hit me with extra fees or hidden costs.

I am earning a 1% reward point after making a credit card payment on my HDFC Bank debit card. I can redeem these rewards, which provide approximately a 0.2% return. I have heard some people get around 0.4% returns. How is this phenomenon possible? If it is true, can anyone explain how?
