Paytm.com is now known to almost every Indian. Thanks to their marketing department. They provide you the best deals right now and also offer cashbacks which is the best marketing strategy. Nowadays offers are a part of marketing and I guess paytm uses it quite intelligently. Paytm now has a vast online shopping store too.
Now coming to my experience. It really good with paytm. Specially when they offer cashbacks on tickets and recharges.
Customer service is really good. They listen to your problem before they start speaking. I faced some difficulties and I dropped a mail they sorted it out within 24 hours. Soo I am very happy with customer service.
Delivery timeliness- Delivery is fast but depends on merchant to merchant. It too depends on the merchant through which courier he is sending and whether its by air or surface. So sometimes things get delayed but sometimes they come faster than expected.
App and website- both of them are user friendly. Even a kid can browse easily through their store and order items. Paytm wallet is one of the best out there in the market. Pretty fast transactions.
Reliability- definitely reliable I don't think you will loose your hard earned money because their team is there to look after it. I case you loose. Make a complaint and things get sorted out faster than before now.
Definitely recommended!
