I have been using this Paytm fort last 1.5 years from my mobile, but I did not get any problem yet.
I like it so much for very good feature like Instantly fund transfer, Instantly Mobile recharge, postpaid bill paying. I fond of this, and I dont want to use any other e wallet system.
I am using for it to pay my telephone bill, online shoppings, online movie ticket booking I never get the any problem, I would like to suggest to all use it and enjoy cashless system with it.
