I like this app because it gives cash back when you buy something from it or when send money to any one or also when you recharge your balance . qualty goods of paytm is average and cheap. peoples who want cheap price products can use it and can also get cash back . but there delivery is slow you will get your goods after many days. but there money back is very fast when you dont like product you can give it back and they will gine money back in between 24 hours
