Paytm is the most useful application or website in todays India having demonetisation. Paytm helped me out with paying electric bills, water bills, recharge up my phone and many more small tasks.My experience with this app from last month is just great.The app is well developed as well as the website is great builded.The webpage loads fast .I have never seen a error on the site like temporarily down.I ordered a pen drive from the app and the delievery was fast and before the date that was given to me.The packaging was great.The customer care service is great, a delayed recharge of my phone was solved by the customer service easily. Must use the app on your smart phone or the website.
