I wont tell flipkart is the worst application for shopping, but according to my experince I faced with flipkart made me to hate it. Once I ordered a mobile from flipkart, it got damaged by the night of the same day and then I returned it by contacting with flipkart customer services.
The customer care executive told that their executive will contact me with in two days and check the condition of the mobile. But none of their officer reached me to check the condition. And finally after 10 days he came, checked the condition and then it was replaced.
