Paytm I have started in January 2017 and it is realy awsome and simple in use you can deposite quickly and buy from paytm and it will give you cashback with its seassion.I have done many times transaction with this it also provides you mobile app and website also.It is very easy to use and do transaction freely.
Its bad thing is that I will say to company is that to keep login is not available in mobile app Whenever I come back it will show to login so please improve this.
Thank you
