[Resolved]  Flipkart — damaged parts received

Address:

I have ordered hitech ro service kit from flipkart.
While installation serviceman found that one part is damaged from inside.
When i called customer care, they told that only un-used item can be replaced and you need to return complete unused kit. One item from the kit can not be returned or replaced. But while installation, some parts have already fitted so that count as used item.
I want to complaint that there should be an option to replace some parts from the order if any item is damaged or replacement should be valid for used item.
