As a long time customer and admirer of Flipkart, I have no hesitation in saying that there is something massively wrong at Flipkart. Earlier FK used to be my goto destination for buying anything online, since last 1.5 years things have changed drastically. Every single product, that i need to buy is either cheaper on Amazon India or is not available at all on FK- every single product.
Customer service that used to be friendly is not welcoming either. On the other hand, Amazon India seems to be obsessed about customer service, they will readily offer you GV for a slightest of mistake on their part. Their product inventory is massive. Essentially Amazon india has become what FK used to be 3 years back and FK seems uninterested in doing business anymore.
Customer service at FlipKart has really gone downhill.
The last couple of times I've reported incorrect listings on FlipKart for books (wrong cover image or wrong author name) I've actually been told "sorry, we can't help you with this."
I ordered a ball on FK and a week later I got an email saying that my order was canceled due to lack of stock. This has happened to me on Amazon as well, but the difference was that the email from Amazon came in a day or two.
Same with me. I almost stopped looking/searching at FK. It is either not available at FK or amazon is little cheaper. I have not purchased anything recently on FK, so can't comment on the customer service.
Amazon is burning much more money than flipkart right now. They have invested more than flipkart's total funding and still doing quarter of Flipkart business. Flipkart on the other side is trying to reduce its loss and trying to do breakeven in few categories.
