I am using paytm last 1 and 1/2 years. Now till date I have faced no problem with this site . delevery of the products is good, return policy is good. Paytm give refund when recharged with this site and apply coupan succesfully. This site is user friendly .
Paytm provided all facility in one place. I am also doing my mobile and tata sky recharge with paytm and I got cash back after succesfull recharge.
