Flipkart — Order not delivered but shown as delivered

I have placed a order with flipkart, when it reached my location i was not available so i told delivery person that keep the parcel on reception. He asked me OTP for the product i have given him. But when i reached the hostel parcel was not there, so i have checked the recording then i realised deliver person has not kept the parcel on reception. when i reached the flipkart customer care for account exceutive number they have not provided me with the same neither helped me with the same. If some how i would have got the number i could have talked.
if needed video of the same i can provide
