Paytm is my favourite site for recharging and for payment of dth and also shopping also I have been using this site from last 2 years and I felt no problem with the site.
Its fast in providing cashback and recharges discount offers are the best in this paytm site and I just use paytm coupons for recharging and I received nearly 200 rs of recharge coupons from paytm and I would say to use this site
