Flipkart — Return pickup cancelled

I placed a order of laptop and was delivered to me on 7th Aug and on 9th I placed a return request for pick up and 17 the Aug was given you me as pick up date in between this I received messages from ekart for pick up but no one came to pick my order then on 18th I called the Flipkart regarding the issue and they gave me 21st Aug as resolution date, but on 18th Aug at evening I received a message from ekart that you return request was cancelled .now I am stuck with a damaged laptop and on app the option of return is also not there
How ekart could do this as without visit g they cancelled the return request.
Now who is responsible for my loss of almost 65000
Ekart service is worst .
