I looted Ladoo few week ago when they were giving 100rs per refer. I made almost 4000rs in Ladooo app. Still, i am daily recharging my dth for Rs300. And it has 400+ balance now. I also looted Flipkart gift vouchers worth Rs3000+ by referring trick. Now they are giving Rs25 per refer. But I'm still looting it. IFS plays an indispensable role in this. I knew about refer offer from IFS. There is a whatsapp group of all IFS members. I got all new things from there.
