The paytm is the worst e commerce app I have ever used, I also used their different app that is paytm mall both were disgusting, I cacelled an order of rupees 350.they send me notification that amount is refunded but when I communicated with my bank, it denided any transfer by ptm, so I called their customer care, which was not so caring and not responding to me, Actually its not a customer care its just a IVR which keep on repeating the same stuff.SO finaly I went on twitter and started twitting against them.and after 2 days finally finally they deposite the money. They troubled many other people also.plz be carefull while using this app
