Flipkart
By my experience flipkart is very bad online shopping app because some times we order other color of product and flipkart deliver another clour of product recently I order black puma shoes and flipkart sand white puma shoes and refund system is aslo very poor and the quality of product is also very bad they sell first copy of brands not original. and some time they cancelled my order automatically. Delivery boy is not call me before delivery every time I am calling to delivery boy for my product I am just frustrated by this company . Amazon is better than flip kart
