The paytm is good and gives great cashback in shopping order . And I also use paytm banks is money transfer, movie, Train tickets and other works. but the paytm mall is not not good because he gives cashback but the quality of product is not good and some tym the product is all different from which you order in colour and in brand .
So I think paytm is doing wrong you maintain the quality and reality of product by any cost .you decrease the cashback in product but please maintain quality beacause the trust is main factor in online shopping .
