Paytm is very usefull nad easy to tranfer money from one to another but at some times this.app does not work properly.once I did a transaction of some amount in my paytm the amount did not came into my account after all the customer care process I got that money after 2 days into my account and if you did not update your account the app again restarts it u have to login again into it.leaving this it is very usefull no tension of carrying cash in pockets.etc. You can also shop in it too and quality is also good. Thankyou
