I use this app since 1 year. And I usually use this app for doing any transactions, whether of bill recharge, or any sim recharge. I prefer it more than any another app .
Bcus it gives hige sum of cashback everytime. And I often use that cashback in recharge. And also in your first bill payment or any recharge you get 100% cashback. So I will suggest u all to give it a try atleast once. And you wont fill disheartened.
