As it is well said that all glitters are not gold.I bought a redmi mi 4 for rs 8500 from flipkart big billion day sale on 21 Sept. and I found that the the phone is not working properly.i just ordered for the replacement and my order is not confirmed yet an it’s 26th today.i am really disappointed with the service of flipkart .I am just surprised that they are one of the best e-commerce sites of india and they are doing such things .I will certainly not recommend anyone to shop with flipkart , just go for amazon or any other sites they have a far much better assistance of their customers .
