Flipkart — Replacement not done by flipkart

Flipkart have worst customer support when it comes to electronic items. I received my order on 3rd Feb. It was a gift to someone. On 4th Feb, I made a replacement request as the phone is not getting charged (Replacement ID:[protected]).Now I am even judging the originality of the product shipped by them. Every few hours a representative calls and schedules a visit then when we are waiting for the person, another call is made saying that visit has been rescheduled. It is not possible for the person I gifted the phone to stay at home all the time just in case flipkart people turn up. I hope they know the meaning of working class. Now, we received a message that you people tried to contact us but we were not available. I do not understand how a person staying at home for your representative is not available. Also if they mean that they were trying to contact us by call, then I want to assure them both phone numbers I mentioned in the order were ON and both can't be unreachable at the same time. Their site is also now customer friendly when it comes to filling a complaint.
