Paytm is not only a recharging app but it's like a mini bank or shopping site.
Paytm always provide good cashback which lacks in other recharge service.
Through paytm you not only just do recharge you can do shopping of anything and you will get cashback on that too. Even you book a bus you will receive cashback and that amount can be used anywhere anytime.
Im daily using paytm and rolling the cash regularly I used some amount are received.
I have brought cloth shoes and the product received is all good and still receiving good products.
As now due to demonitization of 500 and 1000 took place I wasn't getting money I needed in urgency and in a hotel I saw they using paytm so I asked them if they have any changes of 100 and luckily they have it and I asked them to give me some and I'll pay through paytm and they agreed too and I did this in 3 hotel and got good money which I can spend for a week.
So paytm is a must to have app.
