I ordered a megaminx and the piece I recieved is use and its damaged I just cant believe that how that can happen . I would request paytm to take action against it.Talking about concept they give a lot of discount but they send used product and that is directly cheating the customer.App layout and design is good and they show the photo of product and in reality these photo differs a lot from orignality.It has very variety products and we cans ort or filter from these product which is very good thing about it.It is not at all useful for anybody if they cheat like this and dont improve there policies and I would rate them as least as possible .I wouldnt recommend it to anyone go amazon and flipkart and other trusted websites and apps.
