Consumer Redressal

I am trying to find my books from last 14 months, and not getting anything from GATI KEW LTD. I couriered my 8 packets from my college in Bhubaneswar to Lucknow on 18 march 2020, when our college was shut down suddenly due to rise of pandemic. I booked the courier service to move my books and other belongings Out of the 8 packets, I received 7 after 2-3 months and regular chasing of GATI KWE LTD, the courier service I still have not received my 8 packet(which are in a red bag in brown carton), which has my most important books and one book signed by Mr. Ruskin Bond, the great writer. The company said its at their warehouse at kalaghoda warehouse near Gurgaon initially, then they said its lost. The books I have in the packet are most valuable and money as compensation wont do any justice to me, as these books are everything(MBA related books). 3 filed grievance at consumer helpline but even then nothing has been achieved, so finally complaining here as GATI KWE is not responding now Two times NCH has called and asked Gati to help, they did not I registered in National consumer commission, they asked me to register my case here. Someone please help me, I need my books , please help me
