Is there any better way which will help to earn more points on fastag recharge on HDFC Rergalia Gold

Hi experts

Amazon pay vouchers have become less rewarding for regalia gold. Is there any better or cost effective way for fast tag recharge?

Here is the amazon pay calculation. It is actually loss making if I choose for cashback.
