Im using paytm.com from 1 and a half year and im not having a single complaint for this site.even their app is also good and fast in term of service.paytm is widely know for the cashback schemes and coupons.i yesterday got a 100rs cashback on movie ticket.Their customer service is very good as they respond quickly within minutes and they also have a working customer helpline.the quality and service of service is unmatchable.paytm.com is very punctual in terms of delivery time.they are almost on time and rarely package arrive lately.paytm.com app is one of the best as it very fast and easy to use.you can recharge your mobile, pay electricity, broadband and water bill in seconds.overall paytm is very secured and easy to use in daily life.
